软电话 从功能分为：服务器端和客户端 服务器：记录所有客户的信息，对客户的登陆、注销等请求进行响应 客户端：利用UDP协议与服务器和被叫或主叫客户端进行通讯 点对点通讯中的请求和响应消息是通过SIP协议来完成传输的，音频信息（压缩后）是同构RTP协议来完成传输的-Soft phone functionality is divided into: server-side and client-server: a record of all customer information, customer landing, write-offs, such as in response to client requests: the use of UDP protocol with the server and the called or caller client communication point of point communication in the request and response messages through the SIP protocol to complete the transmission, audio information (compressed) is isomorphic RTP protocol to complete the transmission

这是一个用MTTLAB实现的OFDM调制解调系统，其中OFDM信号包括6个子载波，每个符号包括35个比特。整个系统包括线性分组编码，QPSK调制解调，OFDM调制解调等，最后得出在不同信噪比下的误码率曲线，整个系统简单明了，对初学者比较有帮助。
