说明：  利用ode45求解微分方程组。利用马尔可夫状态转移，求解系统部件随时间的可靠性函数。(Use matlab to solve system of differential equations.)

matlab 有限元程序代码,能够供大家学习参考 (matlab finite element program code, good enough for them to learn information)

这是《Space-Time Codes and MIMO Systems》书中第二章的源程序，包括mimo信道模型，遍历容量，中断容量以及发射端或接受端具有相关性等程序。(This is the " Space-Time Codes and MIMO Systems" source book, the second chapter, including mimo channel model, ergodic capacity, the outage capacity and the transmission side or the receiving end of relevant procedures.)

功率谱：直接法，间接法，加窗（hamming ,hanning, 矩形）(Power spectrum: the direct method, indirect method, window (hamming, hanning, rectangle))

Turbo Code, Co-Channel Interference

The Wavelet Neural Network This is simple example for using of modified Morlet neural network. Levenberg-Marquardt with numerical Jacobian calculation implemented. Easy to use with other optimization algorithem e.g GA,PSO, etc. The function "xox_lm" may be useful for other optimization problem easily. The function "xox_jacobian" may be useful for Jacobian calculation easily. The function "NN_fcn" may be used by the evolutionary based neural network. The activation function "modified Morlet" will be replaceable by others.

比较协作通信中AF、DF的性能，有误码率的比较，以及实验值与理论值的比较(Comparison of collaborative communication, the AF, the DF performance, comparison of the bit error rate, and the comparison of experimental and theoretical values)

说明：  拉伸具有调节的功能 大家试试看，我自己在书上总结的( The stretch has adjustment function everybody to try to look that I summarize in the book )
