摘要

针对瑞利衰落信道，提出了一种多相移键控(MPSK)信号的网格编码自适应调制方案，称为自适应网格编码MPSK (ATCMPSK)。该自适应方案基于根据信道条件改变编码/调制(协调)速率。假设接收端信道信息理想且衰落缓慢。结果表明，ATCMPSK在衰落情况下显著改善了MPSK信号的误码率(BER)性能。

Adaptive trellis coded modulation for mobile communications

An adaptive scheme for trellis coded modulation of multiple phase shift keying (MPSK) signals, called adaptive trellis coded MPSK (ATCMPSK), is proposed for the Rayleigh fading channel. The adaptive scheme is based on varying the coding/modulation (codulation) rate according to channel conditions. Slow fading and ideal channel information at the receiver are assumed. It is shown that ATCMPSK results in a considerable improvement in bit error rate (BER) performance of MPSK signals under fading.<>
