摘　　要：调制与编码相结合的调制编码技术已被证明提高信道频谱利用率，达到香农信道容量的一种有效途径，这种技术首先是针对ＡＷＧＮ信号提出的，经过多年的研究，其理论趋于成熟，应用也结出了丰硕的成果，ＩＴＵ不久前通过的Ｖ．３４建议则是该技术的成熟标志，而从近几年的研究看，该技术又有被推广应用非线性信道和衰落信道的趋势。本文将介绍这门技术的发展过程及目前的研究动态。Modulated encoding technology is proved to be an efficient approach to enhance the Spectrum avalibility to reach the Shannon Channel capacity. It is firstly proposed according to AWGN Channel. After years, the theory became mature and many application accomplishments has been obtainted. ITU. V. 34 Recommendation is a milestone of this technology. View from the study of the recent years, this technology is tend to be applied in nonliear channel and fading channel. Thispaper will introduce the history and current development of this technology.
