提出了一种用于数据通信差错控制的级联编码调制方案。该方案是通过级联的里德-所罗门外码和带宽有效的块内码的M进制PSK（相移键控）调制。在加性白色高斯噪声（AWGN）信道下分析了该方案的误码性能。它表明，可以获得极高的可靠性，通过使用一个简单的M进制PSK调制内码和一个相对强大的里德-所罗门外码。本文还提出了一种构造多进制PSK调制分组码的简单方法。构造了一些具有良好最小平方欧氏距离的短M元PSK码。这些码具有网格结构，因此可以用软判决维特比解码算法来解码。该方案特别适用于要求高可靠性的高速卫星通信大文件传输。<<ETX>>
The authors present a concatenated coding modulation scheme for error control in data communications. The scheme is achieved by concatenating a Reed-Solomon outer code and a bandwidth-efficient block inner code for M-ary PSK (phase shift keying) modulation. The error performance of the scheme is analyzed for an AWGN (additive white Gaussian noise) channel. It is shown that extremely high reliability can be attained by using a simple M-ary PSK modulation inner code and a relatively powerful Reed-Solomon outer code. A simple method for constructing block codes for M-ary PSK modulation is also presented. Some short M-ary PSK codes with good minimum-squared Euclidean distance are constructed. These codes have a trellis structure and hence can be decoded with a soft-decision Viterbi decoding algorithm. The proposed scheme is particularly suitable for high-speed satellite communications for large file transfer where high reliability is required.<<ETX>>
