程序实现了直接序列扩频通信系统，简单易懂。(Program realization of the direct sequence spread spectrum communication system, straightforward.)

the comb pilot aided channel estimation in ofdm modulation is considered. the power of pilot subchannels is under the control. The data experience frequency selective channel then the AWGN noise is added to make the situation worse. The bit error rate is ploted versus SNR.

电子科大马岳林在日本做的 数字预失真 代码 非常有用的 (matlab code about digital predistortion very important )

Genetic Algorithm Matlab code with 3 exaples

利用牛顿法数值计算光纤的传播常数，这样利用传播常数与色散的关系，就可以画出光纤的色散曲线(Numerical calculation using Newton' s method the fiber propagation constant, so that the use of the propagation constant and the dispersion relations, we can draw the dispersion curves of optical fiber)
