在MATLAB环境下实现了CDMA通信系统仿真，程序流程为：随机序列产生--WALSH码扩频--BPSK调制--加入（和不加入）高斯白噪声--BPSK解调--WALSH码解扩，对过程波形进行了存储，对加噪与不加噪情况下的解码结果进行了对比，并绘制出信噪比与误码率关系图。(In the MATLAB environment to achieve a CDMA communication system simulation, the program flow as follows: random sequence generated- WALSH yards Spread Spectrum- BPSK modulation- to join (and not to join) Gaussian white noise- BPSK demodulator- WALSH yards Solution expansion of the process of waveform storage, to add noise and without noise cases, the decoding results were compared, and draw out the signal to noise ratio and bit error rate diagram.)

利用第二代小波变换———提升小波变换,为第一代小波变换提供了一种新的更快速的实现方法,使得其构造不再 依赖于Fourier 变换构造,可以实现所有的第一代小波变换,提升方案把此变换过程分为分裂、预测和更新3 个阶段。(--- Second generation wavelet transform using lifting wavelet transform, for the first generation wavelet transform provides a new, more rapid implementation method, so its structure is no longer dependent on the Fourier transform structure, can achieve all of the first generation wavelet transform, enhance the program to the transformation process is divided into split, predict and update the three stages.)
