The limited radio frequency spectrum that can be used for transmission leads to bandwidth and power efficiency being a key requirement in the development of wireless access technology from 3G to 5G today. Data communication technology also requires this as mentioned on high speed network standards such as DSL, WLAN and WMAN with its products ADSL, WiFi and Wimax. In the last few decades we have seen the evolution of the Orthogonal Frequency Division Multiplexing (OFDM) modulation technique used in the technologies mentioned earlier to this day. This technique is regarded as a standard technology for broadband wireless access technology. In hardware implementation, the most preferred by many researchers is the Field Programmable Gate Array chip, as it can be reconfigured. The OFDM technique can be easily implemented because it uses Fast Fourier Transform (FFT) algorithms that are coding and programming capable of reducing the computational time of Discrete Fourier Transform. This paper discusses the implementation of the memory-based 1024-point IFFT / FFT for BWA communications. The design is focused on synthesizing and implementing the system block FFT 1024-point radix-4 using Decimation in Frequency (DIF) method. Implementation for IFFT / FFT 1024-point resource usage slice number 1%, the number of slice flip-flop 1%, the number 4 LUT (Look Up Table) 1%, and the number of IOB 27%. of the FPGA are used.

Adaptive Multimedia

There is a massive upsurge in data traffic over the Internet due to multimedia services. The upcoming heterogeneous broadband wireless access networks (BWANs) provide higher data rates, increased capacity, and enhanced network coverage. Since the smart phone usage and multimedia service demand is increasing at a much faster pace as compared to the capacity and resources of the underlying network technology, adaptive multimedia services are essential to provide satisfactory quality of experience (QoE). The focus of this chapter is to discuss the adaptive techniques to provide better multimedia services to heterogeneous users in next-generation networks. These techniques consist of video streaming optimization using MPEG-DASH, video caching schemes, quality aware video transcoding, web optimization of multimedia services, and user-centric cross-layer optimization.
