可以仿真出2PSK的误码性能，并以此为基础可以仿真出MPSK的误码性能(2PSK can simulate the error performance, and on this basis can be simulated BER performance of MPSK)

在OFDM仿真模型的基础上用MATLAB语言编写出OFDM发送、信道及接收整个系统,在系统仿真正确的前提下,对循环前缀、信道估计等性能改善方法进行进一步仿真验证,得到了预期的理想结果(In OFDM simulation model based on the use of MATLAB language to send the OFDM, channel and receive the entire system, in the system under the premise of the correct simulation of the cyclic prefix, channel estimation methods for further performance improvement simulation, have been expected results)

说明：  用前推回代法求系统潮流，直接运行出结果，得出节点电压。(Directly with power generation method system trend, run out as a result, it is concluded that the node voltage.)
