name:UTKARSH guide: A.S.ABHYANKAR SIR this code is for wavelet transform using lifting scheme. but this code is not having in-place computational capacity.

程序的主要功能是做了一定范围的信噪比下，对每个信噪比：随机信号QPSK调制； 根据Alamouti方案的矩阵进行编码；发送信号经过瑞利信道和加入高斯白噪声； 接收信号采用最大比合并的方法；最后对合并信号进行最大似然判决并求误符号率。 结果表明10^-3对应大约12->13dB(Procedure main function is to do a certain range of SNR for each signal to noise ratio: random signal QPSK modulation program in accordance with Alamouti coding matrix send signals through Rayleigh channel and adding Gaussian white noise received signal using maximal-ratio combining method Finally the combined signal and the maximum likelihood decision for symbol error rate. The results showed that about 10 ^-3 corresponds to 12-> 13dB)

模型，对于利用matlab做反演研究的人来说非常方便，包含纵横波速度，密度(Model, for use matlab to do inversion is very convenient for people, including the shear wave velocity, density)

matlab编程的电子书籍。对想学习matlab的同学比较有用(matlab programming e-books. Useful to the students want to learn matlab)
