In this paper the performance of a Generalized Frequency Division Multiplexing waveform is evaluated when compared to an Orthogonal Frequency Division Multiplexing signal. For the development of the previous waveforms, the GNU radio software and the Software Defined Radio (SDR) equipment USRP N210 are used. Through a spectrum analyzer the power of both waveforms are measured and the Out-of-Band Radiation is analyzed. Then, the results obtained are compared and the advantages and disadvantages of the implementation of GFDM as a waveform within the fifth generation systems are exposed.

Communication is very much important for every community and radio communication is one of the easiest and simple media to provide information. The project represents the full duplex communication mode of FM transceiver (Radio + Transmitter). This paper describes on how to build a short-range FM transmitter using microcontroller. The paper also describes on how to build a FM radio receiver using micro-controller. Through the FM transmitter we can transmit our voice and any audio signal while through the radio receiver listener can listen any FM broadcasting channel. This project is based on KTMicro IC KT0803K monolithic digital stereo FM transmitter and Phillips TEA5767 radio receiver module. The quality of transmission and radio reception can be improved by Digital Signal Processing and Intelligent Tuning System. The heart of this project is Arduino UNO micro-controller which controls slave devices by Inter-Integrated Circuit (I2C) communication. The transmitter and the receiver both supports digital tuning and Phase Locked Loop (PLL) concept is used for recovery of the signals. The transmitter of this digital FM transceiver can be used for making announcements in schools, colleges, industries, hospitals, and other places using a condenser mic amplifier circuit and share music with the FM listeners using audio input port of the FM transmitter module. The radio receiver of this transceiver is used for listening any local FM broadcasting channel. It can be also used in specialized application such as local area network. For the construction of the transceiver it requires some small and low cost external equipment’s.

<p>This paper presents an architecture proposal for a spectrum sensing network using software defined radios. The radios responsible for the sensing are implemented with SDR-RTL, a low-cost radio, capable of receiving signals from several frequency bands, such as those used in FM, DAB and DVB-T. Sensing functions are implemented using GNU Radio, the most commonly used free software for configuring software-defined radios installed in Raspberry Pi’s, which makes the sensing structure significantly compact and inexpensive when compared to other solutions. Experiments are performed to measure the probability of detection in relation to the signal noiseratio, as a metric of the efficiency of the system proposed in this work</p>
