Simulation and Software Radio for Mobile Communications,一本移动通信中软件无线电仿真的书，讲解十分详细。(Simulation and Software Radio for Mobile Communications, a mobile communication radio simulation software books, explained in great detail.)

This is an .m file to use in power system state estimation problems. It has no restriction on the number of network parameters and you only have to follow the format for input data and interpret the output data accordingly. There is a pdf File in spanish explining all the basics of this code. I will try to get an english version ready asap.

关于用MATLAB语言来编写哈夫曼的编码器的程序(Program on the MATLAB language to write the Huffman encoder)

北邮通信仿真教程第10章的源程序，教程网上可以搜到，程序包括BPSK,QPSK的调制解调，载波同步，误比特率的计算等。(Beijing University of Posts and Telecommunications Communication Simulation Guide to Chapter 10 of the source, the Guide can be found online that included BPSK, QPSK modulation and demodulation, carrier synchronization, bit error rate calculation.)

This Matlab Code models a Rayleigh fading channel using a modified Jakes channel model. A modified Jakes model chooses slightly different spacings for the scatterers and scales their waveforms using Walsh–Hadamard sequences to ensure zero cross-correlation. alpha_n = frac{pi(n-0.5)}{2M} and eta_n = frac{pi n}{M}, results in the following model, usually termed the Dent model or the modified Jakes model: R(t,k) = sqrt{frac{2}{M}} sum_{n=1}^{M} A_k(n)left( cos{eta_n} + jsin{eta_n} ight)cos{left(2pi f_d t cos{alpha_n} + heta_{n} ight)}. The weighting functions A_k(n) are the kth Walsh–Hadamard sequence in n. Since these have zero cross-correlation by design, this model results in uncorrelated waveforms. The phases ,! heta_{n} are initialized randomly and have no effect on the correlation properties. Matlab fast Walsh-Hadamard transform function is used to efficiently generate samples using this model.
