Recent discussions on viable technologies for 5G emphasize on the need for waveforms with better spectral containment per subcarrier than the celebrated orthogonal frequency division multiplexing (OFDM). Filter bank multicarrier (FBMC) is an alternative technology that can serve this need. Subcarrier waveforms are built based on a prototype filter that is designed with this emphasis in mind. This paper presents a broad review of the research work done in the wireless laboratory of the University of Utah in the past 15 years. It also relates this research to the works done by other researchers. The theoretical basis based on which FBMC waveforms are constructed is discussed. Also, various methods of designing effective prototype filters are presented. For completeness, polyphase structures that are used for computationally efficient implementation of FBMC systems are introduced and their complexity is contrasted with that of OFDM. The problems of channel equalization as well as synchronization and tracking methods in FBMC systems are given a special consideration and a few outstanding research problems are identified. Moreover, this paper brings up a number of appealing features of FBMC waveforms that make them an ideal choice in the emerging areas of multiuser and massive MIMO networks.

UFMC (Universal Filtered Multi-Carrier) is a novel multi-carrier transmission technique that aims to replace the OFDM (Orthogonal Frequency Division Multiplexing) modulation technique for fifth generation (5G) wireless communication systems. UFMC, being a generalization of OFDM and FBMC (Filter Bank Multicarrier), combines the advantages of these systems and at the same time avoids their main disadvantages. Using a Matlab simulation, this article presents an analysis of the robustness of UFMC against fading effects of multipath channels without using a CP (cyclic prefix). The behavior of the UFMC system is analyzed in terms of the PSD (Power Spectral Density), BER (Bit Error Rate) and MSE (Mean Square Error). The results show that UFMC reduces the out-band side lobes produced in the PSD of the processed signal. Also, it is shown that the pilot-assisted channel estimation method applied in OFDM systems can also be applied in UFMC systems.

Filter bank multicarrier (FBMC) is one of the effective candidates for the fifth generation of wireless communication networks. 5G (5th-generation wireless systems) is accepted as the next major stage of mobile telecommunication technology. The extent of 5G will be expanded mobile broadband services to next-generation automobiles and connected machines. In particular, filter bank multicarrier with offset quadrature amplitude modulation (FBMC/OQAM) is determined as the future generation 5G air interface by researchers recently. Filter bank multicarrier (FBMC) is admitted as one of the alternative technologies for multicarrier modulation. Compared to orthogonal frequency-division multiplexing (OFDM), FBMC has better spectrum shape and supports mobility. Therefore, efficient hardware implementations have highly interested researchers. Cyclic prefix (CP) and guard band are used for orthogonal frequency-division multiplexing (OFDM) and this causes loss of spectral efficiency, but FBMC applications do not need CP and guard band. Due to the fact that FBMC has offset QAM (OQAM) and band-limited filtering features on each subcarrier, the need for CP and guard band is eliminated. In this paper, novel pipelined hardware architecture of the filter design of FBMC/OQAM modulator has been proposed.

The coexistence of multiple air interface variants in the upcoming fifth generation (5G) wireless technology remains a matter of ongoing discussion. This paper focuses on the physical layer of the 5G air interface and provides a harmonization solution for the joint implementation of several multicarrier waveform candidates. Waveforms based either on cyclic prefix-orthogonal frequency division multiplexing (CP-OFDM) or on filter bank multicarrier (FBMC) are first presented through a harmonized system model. Complexity comparisons among five different waveforms are provided. Then, the complexity of a proposed configurable hardware implementation setup for waveform transmission and reception is evaluated. As a result, the harmonized transmitter and receiver exhibit 25–40% and 15–25% less complexity in floating-point operations, respectively, in comparison to two standalone implementations of the most complex waveform instances of the CP-OFDM and FBMC families. This highlights the similarities between both families and illustrates the component reuse advantages associated with the proposed harmonized solution.

Saat ini, teknologi pada bidang telekomunikasi berkembang dengan pesat. Pengguna telekomunikasi membutuhkan teknologi komunikasi yang cepat dengan bandwidth yang lebih lebar. Oleh karena itu dikembangkanlah Filter Bank Multi Carrier/Offset Quadrature Amplitude Modulation yang merupakan teknologi kandidat modulasi yang akan digunakan pada 5G. Filter Bank Multi Carrier/Offset Quadrature Amplitude Modulation (FMBC/OQAM) merupakan perkembangan dari Orthogonal Frequency Division Multiplexing (OFDM) yang dimodifikasi dengan menggunakan filter untuk mengurangi noise. OFDM menggunakan teknik multiplexing yang membagi bandwith menjadi beberapa frekuensi sub-carrier. Tetapi OFDM memiliki kelemahan yaitu memerlukan Cyclic Prefix (CP) untuk mengatasi Intersymbol Interference (ISI) serta Intercarrier Interference (ICI). Dengan menggunakan Filter berdasarkan Lembaga Physical layer for dynamic spectrum access and cognitive radio (PHYDYAS)  ,lebar bandwith yang bertambah akibat Cyclic prefix  akan dapat dikurangi Hasil yang dicapai dalam penelitian ini adalah  FBMC berhasil diterapkan  dan data yang dikirim sama dengan data yang diterima.

The teaching efforts at Marriott Library are distributed widely across a variety of groups and a range of subject matter. Teaching styles and pedagogical foci are varied and diverse among the librarians in the building. To increase collaboration and raise teaching standards, Graduate and Undergraduate Services (GUS) formulated Guidelines for teaching librarians by using the University of Utah’s Quality Course Framework (QCF) and Marriott Library’s own Four Core Student Library Learning Outcomes and mapping them to the Association of College and Research Libraries (ACRL) Framework for Information Literacy for Higher Education. To facilitate communication and usability, the Guidelines contain an alignment matrix for librarians to follow through the teaching process. The matrix is also intended to open up new opportunities for conversation and collaboration between librarians and academic staff to better serve student needs. The purpose of this report is to document and reflect upon the collaborative work done by teaching librarians at the University of Utah to create the Teaching Guidelines. The process of this work involved the synthesis and alignment of several models of pedagogical structure as well as the overarching interests and goals of a variety of stakeholders and participants in the teaching environment at the University. The product of these efforts includes clear Teaching Guidelines, alignment with the ACRL Framework for Information Literacy, and an alignment matrix designed to provide a clear map of the teaching philosophies and strategies employed at the library. This report presents the process of creating and implementing the Guidelines and outlines the background of the process, including those institutional, situational, and environmental circumstances which shaped the general course of its development. The report includes an analysis of the pedagogical characteristics of the Guidelines. The report also presents an example of the Guidelines as used in action when developing the library-related content for an undergraduate-level community learning course known as ‘Learning, Engagement, Achievement and Progress’ (LEAP).

Filter Bank Multicarrier (FBMC) is a multitone modulation technique that is expected to replace the Orthogonal Frequency Division Multiplexing (OFDM) due to its inherent characteristics that makes it immune to channel dispersive effect on the transmitted signal in both time and frequency. The most effective ingredient in the FBMC is the pulse shaping that the OFDM symbol lacks. In this paper, a comparative study is presented between different pulse shapes used in the FBMC like the RRC, PHYDIAS, IOTA and Hermite function alongside the conventional OFDM.

Howard Turner Barnes rapidly came to prominence for his part in the high precision basic experiments in classical physics which first set an international standard in the science at McGill University. Most noteworthy are his determinations of the mechanical equivalent of heat and of the specific heat of water over the full range of temperature. Later he studied ice formation and became world famous, not only for his highly original and practical methods for the removal of ice jams, but for the great skill with which he used them. Born at Woburn, Massachusetts on 21 July 1873, Howard was the son of Reverend William S. Barnes, LL.D., and of Mary Alice ( Turner). At the age of six he came to Montreal with his parents. Here his father founded the Unitarian Church and is remembered as a noted clergyman of his time. Howard was tutored by Reverend John Williamson and attended Montreal Academy before entering McGill University. He received the degree of B.A.Sc. in 1893, just as the new Macdonald Physics Building was completed. Barnes immediately began a series of coordinated and well-sustained fundamental researches while at the same time holding posts in the University of rapidly increasing rank. He was appointed Macdonald Professor of Physics and Director of the Laboratory at the early age of thirty-four. Professor Barnes selected important research problems and quickly grasped the real practical difficulties of each problem in complete detail. While courage, imagination and resourcefulness were essential, the great amount of work done in a relatively short period demonstrates an intuition that was unfailing throughout his scientific life. The dispatch with which the work proceeded equally well in the laboratory or in the field cannot be dissociated from the nobility of Professor Barnes, and his charming simplicity.

Simulation Results

Computational complexity is one of the key factors considered for evaluating transmitter performance of future 5G applications. In this contribution we have chosen Filter Bank MultiCarrier (FBMC) as it is the most possible candidate to replace/coexist with the Orthogonal Frequency Division Multiplexing (OFDM) modulation. In the literature two main design approaches can be found for FBMC: Frequency Spreading (FS) and PolyPhase Network (PPN). From these two structures numerous schemes were derived. These schemes are studied and the complexity (real multiplications and additions) for each scheme is compared. Based on the complexity calculations, the simulation results show that PPN has a better complexity performance compared with FS. Also, the alternative PPN schemes have significant improvement in complexity compared to the standard PPN.
