光子晶体的电场的分布图的程序，可以显示场的分布图。(The program of the distribution of electric field in photonic crystals)

matlab和optisystem联合调试用的误码率计算程序，经过测试，使用简单。(matlab and optisystem debug the error rate calculation procedure, tested, simple to use.)

是黄鄂教授的原版论文，主讲希尔伯特黄变换的，很有用的，大家可以看看(it is very useful for singal process)

一个四用户的扩频通信系统，扩频增益为N=16，采用Walsh码进行直接序列扩频，BPSK调制，无线信道为AWGN信道。在接收端进行解扩，解调，判决，通过仿真得到其中一个用户的误比特率与信噪比的仿真结果。(A four-user spread spectrum communication system, spreading gain for N = 16, using Walsh code Direct Sequence Spread Spectrum, BPSK modulation, AWGN channel for the wireless channel. At the receiving end for despreading, demodulation, judgments, through the simulation to be one of a user' s bit error rate and SNR of the simulation results.)
