Digital Broadcasting

Advances in wireless communications have enabled various technologies for wireless digital communication. In the field of digital radio broadcasting, several specifications have been proposed, such as Eureka-147 and digital radio mondiale (DRM). These systems require a new spectrum assignment, which incurs heavy cost due to the depletion of the available spectrum. Therefore, the in-band on-channel (IBOC) system has been developed to work in the same band with the conventional analog radio and to provide digital broadcasting services. This paper discusses the function and algorithm of the high definition (HD) radio frequency modulation (FM) digital radio broadcasting system. Content includes data format allocation, constellation mapping, orthogonal frequency division multiplexing (OFDM) modulation of the transmitter, timing synchronization, OFDM demodulation, integer and fraction carrier frequency (integer carrier frequency offset (ICFO) and fractional CFO (FCFO)) estimation, and channel estimation of the receiver. When we implement this system to the field programmable gate array (FPGA) based on a hardware platform, both theoretical and practical aspects have been considered to accommodate the available hardware resources.

The Way

In the field of marketing, it is in need of adequate media to convey its business promotional messages. The atmosphere of competition makes various promotional patterns to attract consumers as much as possible. Advertising, for example, this one has the characteristics and need a delicate consideration for the selection of suitable media. Advertising media that is common instead of television and print is radio. Radio ads have their own characteristics compared to other media. The company's effort to create satisfaction can be done through the quality of service provided. The maximum quality of service directly can give the maximum consumers' expectation. By having good service quality then they can fulfil all forms of demand for products or services offered to consumers. Quality of service in accordance with the expectations of consumers by itself will support the company's efforts in order to achieve the goals set by the company both short and long-term, including in the business of radio broadcasting. In the end, it can influence the listener behaviour. Da'wah is the way to invite, call and influence people to always adhere to the teachings of Allah SWT in order to obtain the happiness of life in the world and hereafter. Inviting to the way of Allah SWT is our obligation. The success of his invitation reflects the prospect and preservation of future Islamic developments, for the advancement and retreat of religion rests with the adherents of His followers.

The Difference

This work studied the influence of MPEG-4 HE-AAC v.2 and MPEG-4 xHE-AAC compression algorithms on the reproduction performance of high-quality audio signals. The first part of the article is based on the analysis of earlier publications, studied quality of the compression algorithms for MPEG-4 ISO/IEC 14493-3 (AAC, AAC+SBR, PS, AAC+SBR+PS) and MPEG D Surround standards applied in MPEG-4 HE-AAC v.2 and MPEG-4 xHE-AAC codecs of DAB and DRM systems for digital audio broadcasting, respectively. It has been demonstrated that their use for processing of high-quality audio signals in the frequency range of 40…15000 Hz, allowed to reduce the digital-data rate at the output to 24…30 êbit/s, without observing noticeable phenomena. This conclusion was confirmed in the second part of the article, which described the results of relative comparison of the quality of reproduction of audio signals broadcasted via analogues FM or digital DRM channels. The equipment employed for their realization was described, as well as the methodology to obtain test recordings in order to perform the statistical data analysis. Further, the specific data scales were shown to evaluate the signal pairs being compared. Results of the experiments and their analysis confirmed that, for a digital data rate of 30 êbit/s obtained at the output of the MPEG-4 xHE-AAC coder, the difference in quality was rather weak for audio signals ranging from 40 to 15000 Hz, broadcasted via both analogues and digital channels. In addition, only a marginal difference was noticed for the signal pairs received from the digital output channels of the transmitter processor and DRM receiver. It has been demonstrated that the MPEG-4 xHE-AAC codec, compared to the previous MPEG-4 HE-AAC v.2 version, exhibited clear advantages for practical applications in terms of sound quality. Based on the gained experience, common criteria of deterioration of the data quality were formulated and generalized for all audio compression MPEG standards.

If the customer is greater than acceptable level of service, the cutomer is not satisfied. Conversely, if an acceptable level of service greater than the expectations of customers, the customer will be satisfied. This means that if Bank BRI branch Fatmawati can improve service quality to its customer it will affect the level of satisfaction. In this research found evidence that, in terms of the creation of quality services, Bank BRI branch Fatmawati is one of the branches that participate to implement the established policies and service in accordance with the exiting service standard in the banking world. Amount of influence the determination of quality of service policies applied by the Bank BRI branch Fatmawati indicated by r2. r2 value only 45 % and the rest 55 % influenced by other variables not studied. Meanwhile, the variable relationship of service quality to customer satisfaction can be seen from the values r = 0,67. This shows the value of the correlation coefficient between the variables of service quality to customer satisfaction. This means there are strong relationships between the independent variable X (quality of service) to the dependent variable Y (customer satisfaction). Since r = 0,67 (67 %) greater then 50 %.

Business banking is a service business based on principles of trust and t5he customer is a major asset. Under conditions of business competition among banks strict bank that has resulted in only a competitive advantage (compatative advantage as well as a competitive advantage) who can reach the highest position in the eyes of cusmers or the public. Competitive advantage can be obtained from the quality of customer servicr, so the focus on customers (customer focus), responsive to the development of customer desires and continuously innovate is an acitivity that can be done to anticipate the cimpetitive conditions. In this case, the bank should always evaluate the quality of service given to customers and is reflected in the level of customer satisfaction obtained. Rate the quality of service branch of bank syariah mandiri bogor whole is still under service, because it still was below expectations, this is evident also that the general level of service is still not meeting customer expectations, because the level of hope (expectation0 the customer is generally higher than the level of performance (perfromance) or perception(perception)customer.        Empathy dimension of service quality dimensions are most critical or have any impact on the most powerful influence on the level of satisfaction. In this case, the willingness og bank syariah mandiri branch bogor provide individual attention in serving its clients is crucial. Empathy dimension attributes inclide individual attention, operational time , personal attention, giving interests, and understand the needs. These attributes is the main priority of service quality improvements are intensive and comprehensive.           Customer service strategy to be implemented by the management of bank syariah mandiri in perspective five dimensioris of service quality(tangibles, realiability,responsiveness, assurance and empathy) looks not optimal. In an effort to provide the best service (service excellence) and focus to the customer(customer focus), then the customer satisfaction can be obatained with significantly improved and the improvement of quality of serivice aspects and impticalions of the strategy need to be consldered
