一、引言最佳接收机的理论是用以解决这个问題:从统计接收到的干扰信号中,尽可能细致地判别原发射的信号。每当任务提出后,就要分清“检波”与“取样”的关系。检波时必须分清:信号是否存在,这时也要注意提取一定的接收瞬时信号的数值。解决取样的问題,也可这样来进行:为代替信号的变 I. INTRODUCTION The theory of the best receiver is to solve this problem: In the interference signal received from the statistics, the original transmitted signal should be judged as carefully as possible. Whenever the task is proposed, we must distinguish between the “detection” and “sampling” relationship. Detection must be distinguished: the signal is present, then also pay attention to extract a certain value of the receiving instantaneous signal. Solve the sampling problem, but also to do this: to replace the signal change
