摘要

针对QAM的码信号映射和编码,定义和描述了网格编码调制(TCM)。本文还概述了TCM的发展和基本原理,以及TCM方案如何在不扩展带宽的情况下实现编码增益。用一个例子来说明这种编码方案的一个简单实现。

A tutorial on convolution coding for M-ary signals-trellis-coded modulation
Trellis-coded modulation (TCM) is defined and described with respect to code-to-signal mapping and coding for QAM. Also summarized are the evolution and underlying principles of TCM and how TCM schemes achieve coding gains without bandwidth expansion. An example is used to illustrate a simple implementation of such a coding scheme.<>
