內容簡介

　　大多數(shù)介紹信息論和編碼學的書，不是太過學術化，就是太過簡單。本書避免了上述缺點，既考慮到了數(shù)學的嚴謹性，又充分考慮了易讀性。本書的主要特點詳細介紹了網格編碼調制（TCM）．并重點介紹了加性高斯白噪聲（AWGN）和衰退倍道。以大量示例仔細描述了信源編碼。深入討論了TurboCode。簡要介紹了線性代數(shù)。通過精心挑選的115道例題及115道練習題，清晰透徹地講解了深奧的理論知識和定義。通過大量篇幅論述了密碼學，包括基本原理。私鑰和公鑰密碼，當今通用的加密標準及最新發(fā)展趨勢。 “敘述流暢，通過大量示例及精確的解說透徹地論述了各個主題?！?——審稿人作者簡介 RanjanBose子賓夕法尼亞大學獲得博士學位，現(xiàn)在是德里印度理工大學的副教授，他曾任加州圣何塞的聯(lián)合半導體公司的高級設計工程師。
