射频方面的资料，里面有详细的M文件，希望对大家有用。(Radio frequency information, there are detailed paper M, in the hope that useful to everyone.)

ofdm 的仿真与实现，可以直接运行的，run为运行文件(ofdm fangzhenyushixian)

OFDM,802.11的残余相位补偿算法，用于分析非理想同步的情况(OFDM, 802.11 residual phase compensation algorithm, is used to analyze the situation of non-ideal synchronization)

巴特沃斯滤波器设置，自行设置阶数、截止频率等滤波器参数(butter-worth filter)

这是HMM的语音识别不用修改就可以使用，很好用希望大家喜欢(This is a HMM speech recognition can be used without modification)

for fem matlab for solving all 2D and 3D problem

基于瞬时无功功率的ip_iq检测算法的matlab仿真实例。(Simulation based on instantaneous reactive power matlab)

基于光正交码构造了一类新的不规则00c—LDPc码．新的LDPC码是准循环码，其编码复杂度与码长成 线性关系，具有编码复杂度低的特点，它所对应的双向图中没有四线循环．用和积译码算法对新的码字进行了仿 真，结果表明，与具有类似参数的随机码和规则OOc—LDPc码相比，当信道误码率为10。5时，译码增益分别为 0．3和0．15 dB．(Construct a new class of irregular the 00c-LDPc code based on optical orthogonal codes. LDPC codes are quasi-cyclic code, its complex coding with code length linear relationship, with low encoding complexity, the corresponding bidirectional Figure it in four-wire loop. Simulation with integrated decoding algorithm of the new code word, the results show that when the channel bit error rate, compared with the random codes with similar parameters and rules OOc-LDPc code decoding gain were 10.5 0.3 and 0.15 dB.)

说明：  传输矩阵法计算一维光子晶体带隙图的程序，很好用(Transfer matrix method to calculate one-dimensional photonic band gap diagram of the process, a very good use)
