中文说明：由于一直在做跳频通信信号处理方面的，但网上找到的BPSK调制代码并不能直接用于跳频信号处理中，故自己写了一个跳频信号的BPSK调制代码。
English Description：
Because we have been doing the signal processing of frequency hopping communication, but the BPSK modulation code found on the Internet can not be directly used in frequency hopping signal processing, so I wrote a BPSK modulation code of frequency hopping signal.
