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.

关于OFDM系统仿真分析，使用16QAM调制解调，包括加窗、傅里叶变换。(For simulation analysis of OFDM system, 16QAM modulation and demodulation are used, including windowing and Fourier transform.)

一个经典的LMS程序，是一个M函数程序，可自己编写主程序调用(A classic LMS procedures, is an M function procedures, the preparation of the main program can call their own)

高等应用数学问题，是关于matlab 基础的一本好书。(Advanced application of mathematical problems, is based on the matlab a good book.)

基于MATLAB语言的局部增强的程序，供大家参考，适合入门者(MATLAB language based on local enhanced procedures for your reference, suitable for beginners)

由于系统因素之间关系非常复杂，特别是其表面现象及变化的随机性、模糊性和灰色性，使人们在观察、分析、预测和决策时得不到足够的信息，找不到主要矛盾，从而给复杂系统的系统分析带来困难。这就需要灰色关联分析。(Because the system is very complex relationship between factors, especially changes in the surface phenomena and random, fuzzy and gray so that people in the observation, analysis, forecasting and decision-making can not get enough information, can not find the main contradictions thus to the complex system of systems analysis difficult. This requires gray relational analysis.)
