《通信学报》一九八一年第一期刊载了“双平稳时变信道的序列检测”一文(以下简称[1])。我们读后,感到以下几点需要提出来与作者商讨。为方便起见,在提出问题时我们完全沿用[1]中给定的术语、记号和公式编号。 1.在利用复变函数论中计算围道积分的方法来得到理想接收机二元差错概率P_6的表达 The first issue of “Journal of Communications” in 1981 published the article entitled “Sequence Detection of Bistable Time-Varying Channels” (hereinafter referred to as [1]). After reading, I feel the following points need to be raised to discuss with the author. For convenience, we fully follow the terms, notations, and formula numbers given in [1] when asking questions. 1. In the use of complex function theory to calculate the circumference of points to get the ideal receiver binary error probability P_6 expression
