商品描述

Recent developments such as the invention of powerful turbo-decoding and irregular designs, together with the increase in the number of potential applications to multimedia signal compression, have increased the importance of variable length coding (VLC). Providing insights into the very latest research, the authors examine the design of diverse near-capacity VLC codes in the context of wireless telecommunications.

 

The book commences with an introduction to Information Theory, followed by a discussion of Regular as well as Irregular Variable Length Coding and their applications in joint source and channel coding. Near-capacity designs are created using Extrinsic Information Transfer (EXIT) chart analysis. The latest techniques are discussed, outlining radical concepts such as Genetic Algorithm (GA) aided construction of diverse VLC codes. The book concludes with two chapters on VLC-based space-time transceivers as well as on frequency-hopping assisted schemes, followed by suggestions for future work on the topic.

  • Surveys the historic evolution and development of VLCs
  • Discusses the very latest research into VLC codes
  • Introduces the novel concept of Irregular VLCs and their application in joint-source and channel coding

商品描述(中文翻譯)

近期的發展,如強大的渦輪解碼和不規則設計的發明,以及對多媒體信號壓縮應用的潛在增加,提高了可變長度編碼(VLC)的重要性。本書提供了最新研究的見解,作者們在無線電信背景下研究了各種接近容量的VLC編碼的設計。

本書首先介紹了信息理論,然後討論了常規和不規則可變長度編碼及其在聯合源和信道編碼中的應用。使用外部信息傳輸(EXIT)圖分析創建了接近容量的設計。本書還討論了最新技術,概述了基因算法(GA)輔助構建多樣化VLC編碼等激進概念。最後兩章介紹了基於VLC的時空收發器以及頻率跳躍輔助方案,並提出了未來研究該主題的建議。

本書還包括以下內容:
- 概述了VLC的歷史演變和發展
- 討論了最新的VLC編碼研究
- 引入了不規則VLC的新概念及其在聯合源和信道編碼中的應用
