小波包在信号时频分析中的应用，计算得而他信号小波变换的时频面(Wavelet packet time-frequency signal analysis, he calculated wavelet transform time-frequency plane)

说明：  瑞利衰落信道中空时编码仿真程序： 1.2根发射天线、1根接收天线2.最高信噪比为12dB，即仿真范围为0dB到12dB3.在每个信噪比条件下,误符号数超过20即停止该信噪比条件下的仿真4.每一帧数据为24个QPSK符号(Rayleigh Fading Channels Space-Time Coding Simulation Program: 1.2 transmission antennas, a receiving antenna 2. The highest SNR 12dB, that is, simulation range of 0dB to 12dB3. In each signal to noise ratio conditions, the number of symbol error over 20 that is, to stop the signal to noise ratio under the conditions of simulation 4. each frame 24 QPSK data symbols)
