Salient Features: First Chapter: General introduction to cellular mobile system with its evolution generation-wise is presented. Basic principle of mobile communication and architecture is also discussed in this chapter. Second Chapter: This chapter concern primarily with the problems of digital communication through multi- path fading channel and its channel characterization. Third Chapter: Basic principle of CDMA with coding and spread spreading of spectrum is discussed in this chapter. Problems with transmission and reception of data in AWGN channel are also discussed. Fourth...

As a promising technique, OFDM has been widely used in many new and emerging broadband communication systems, such as digital audio broadcasting (DAB), high-definition television (HDTV), wireless local area network (IEEE 802.11a and HIPERLAN/2). However, as the OFDM signals are the sum of signals with random amplitude and phase, they are likely to have large PAPR that requires a linear high-power- amplifier (HPA) with an extremely high dynamic range, which is expensive and inefficient. Furthermore, any amplifier nonlinearity causes ...

This book examines the latest developments in AI-based metaheuristics algorithms with applications in information security for digital media. It highlights the importance of several security parameters, their analysis, and validations for different practical applications.
