摘要
本文研究了调频调相信号集的格形编码信号，在瑞利衰落信道上的误码性能．并在此条件下，导出误码率的实用表达式，且给出格形编码的例子．
In this poper,the error performance of trellis coded frequency and phase modulated signalsets is inveStigated on the rayleigh fsding channels. And under this condition the practical expressionsof error probability are deducted and an example of trellis coded given.
