摘要
首先介绍了Ｌｅｅ氏码这种对相位透明的多进制线性纠错码的性质和构造，然后将它的应用从ＰＳＫ（移相键控）推广到６４ＱＡＭ系统，并给出性能比较分析结果。
This paper introduces the characteristics and construction of a multi level linear error correcting code——Lee code, which is transparent to phase ambiguity. Then the application of Lee codes is extended from PSK to 64QAM systems. Finally, a performance comparison between transmission systems with and without Lee codes is made, and the results are analyzed.
