计算小波分解后的能量及小波熵。里面还有OFDM信号和WPM信号的程序。-After calculating the energy of wavelet decomposition and wavelet entropy. There is also OFDM signal and the WPM signal process.

此程序是我根据ML估计算法改进的OFDM信号CP检测的代码。-This is the code of OFDM signal detection method on CP improved by ML estimate.

在发射端产生OFDM信号，生成信号的波形已被画出。-OFDM signal generated at the transmitter side, the signal generated waveform is drawn.

Here, wavelets are used in Orthogonal frequency division multiplexing. Wavelets are small waves having amplitude increase starting zero and reduces back to zero. In conventional OFDM, IFFT is used at the transmitter side and FFT is used at receiver.
