一个winsock网络通信程序，实现单向的身份认证，还不构完善

一个winsock网络通信程序，实现单向的身份认证，还不构完善--A Winsock communication program. It implements one-way identity verification. But it is not complete yet.

基于扩频通信的程序，主要是实现了pn编解码、调制、去噪、时延等功能，功能基本都实现了。-Based on the program spread spectrum communication, mainly to achieve a pn encoding and decoding, modulation, de-noising, delay and other functions, basic functions are realized.
