重点研究 了低信噪比﹑多径瑞利衰落信道条件下，基于高阶累积量的OFDM信号盲识别技 术。提出了利用奇数阶累积量区分OFDM信号与单载波信号的方法，并对基于三 阶和五阶累积量的算法进行了仿真分析。 (﹑ Focus on the low SNR multipath Rayleigh fading channel conditions, based on cumulant OFDM signal blind identification technology. Made a distinction between the use of odd-order cumulants single-carrier OFDM signal with the signal approach, and based on the cumulative amount of third-order and fifth-order algorithm for the simulation.)

服务器端通过socket()系统调用创建一个Socket数组后(即设定了接受连接客户的最大数目)，与指定的本地端口绑定bind()，就可以在端口进行侦听listen()。如果有客户端连接请求，则在数组中选择一个空Socket，将客户端地址赋给这个Socket。然后登录成功的客户就可以在服务器上聊天了。-Server-side through the socket () system call to create a Socket after the array (that is set to receive the maximum number of connected customers), with a specified local port to bind bind (), will be able to listen on port listen (). If the client has to connect the request, then select an empty array Socket, the client address assigned to the Socket. And then sign in the success of customers can chat on the server.
