摘要

本文提出了一种基于涡轮码与带宽有效调制相关联的新型编码方案。结果表明，该编码方案在高斯信道和瑞利信道上均能获得较高的编码增益。在高斯信道上，在误码率(BER)为10/sup -6/时，它比64态栅格编码调制(TCM)高出2.5 dB。在瑞利衰落信道上，它的性能优于针对该环境优化的64态TCM。

Turbo-codes and high spectral efficiency modulation

This paper presents a new coding scheme based on the association of a turbo-code with a bandwith efficient modulation. It is shown that the new coding scheme provides a substantial coding gain both on Gaussian channels and Rayleigh channels. On a Gaussian channel, it outperforms 64-state trellis-coded modulation (TCM) by 2.5 dB at the bit error rate (BER) of 10/sup -6/. On a Rayleigh fading channel, it outperforms 64-state TCM optimized for that environment.<>
