利于MATLAB实现OFDM的发送和接收，具体过程发送端先通过QPSK调制，之后进行IFFT变换，然后再添加循环前缀，接收端是一个逆过程。该程序还有另外一个的功能是信道估计，最小乘与卡尔曼滤波器的比较。(MATLAB is helpful to realize the sending and receiving of OFDM. The sending end of the specific process is firstly modulated by QPSK, followed by IFFT transformation, and then cyclic prefix is added. The receiving end is an inverse process. Another function of the program is channel estimation, least - multiplication and kalman filter comparison.)
