WVD变换的matlab工具包，非常有用的信号时频分析工具(WVD transform matlab toolkit, a very useful time-frequency analysis tool)

OFDM信号在无线通信中会受到多普勒频移的影响，从而影响了OFDM信号的正交性，引起载波间的干扰和OFDM信号符号间的干扰，本代码先形成含有N个二进制码元的信号，而这个信号的前半部分和后半部分的信号是一样的，然后根据把这个信号调制成OFDM信号，最后接收端根据这个OFDM信号估计出多普勒因子(OFDM signal in a wireless communication will be subject to Doppler shift of influence, thus affecting the OFDM signal orthogonality, causing interference and interference between the OFDM signal symbol between carriers, the code first formed comprising N binary symbols signal, and the first and second halves of this signal is the same signal, and then the OFDM signal according to the estimated Doppler factor modulates the signal to the OFDM signal received, the last side)
