摘要

本文提出基于格状编码调制（ＴＣＭ）的不等差错保护（ＵＥＰ）１６ＱＡＭ（正交幅度调制）方案和６４ＱＡＭ方案，与通常的ＭＱＡＭ相比，ＵＥＰＭＱＡＭ方案的不重要数据可获得稍好的误码性能，而重要数据可获得９－５４～１１－４６ｄＢ的渐近编码增益．欧洲的地面数字电视标准采用多分辨率广播，本文研究ＵＥＰＭＱＡＭ在正交频分多路复用（ＯＦＤＭ）数字电视地面广播系统中的应用

Abstract

QAM（Quadrature Amplitude Modulation） and 64QAM schems with unequal error protection（UEP） that are designed using trellis coded modulation （TCM） are proposed in this paper.Compared to conventional uniformly spaced MQAM

the important data can obtain 9 54～11 46 dB of asympotic coding gain

with negligible advantage for the less important data.Multiresolution broadcasting techique is adopted by European terrestrial digital TV standard.UEP 16QAM and UEP 64QAM for application in terrestrial broadcasting system of orthogonal frequency division multiplexing （OFDM） digital TV are also investigated in this paper.
