商品描述

This book is an excellent reference for those working in the broad fields of communication theory, information theory, and modem design. It is essential for researchers in modulation and coding for voiceband telephone line modems; signal constellation design; nonlinear precoding for modems; and trellis coding.
The author presents the theory behind the new modulation and coding techniques included in ITU-T Recommendation V.34. Topics discussed include signal constellation shaping by shell mapping, nonlinear precoding, four-dimensional trellis codes, and fast equalizer training by using periodic sequences and FFT methods. In addition, several approaches that were considered but not accepted are presented including trellis shaping, trellis precoding, and modulus conversion.

商品描述(中文翻譯)

本書是從事通信理論、信息理論和調製解調器設計等廣泛領域的專業人士的優秀參考資料。對於從事語音頻帶電話線調製解調器的調製和編碼研究者來說，這本書是必不可少的；它涵蓋了信號星座設計、調製解調器的非線性預編碼以及格碼編碼等主題。

作者介紹了包含在ITU-T建議V.34中的新調製和編碼技術背後的理論。討論的主題包括通過外殼映射進行信號星座塑形、非線性預編碼、四維格碼以及使用周期序列和快速傅立葉變換（FFT）方法進行快速均衡器訓練。此外，還介紹了幾種考慮過但未被接受的方法，包括格塑形、格預編碼和模數轉換。
