Modeling-Rayleigh-fading-channel-based-on-modifie
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.

fractal-interpolation_sucess
分形差值函数是由迭代函数系统IFS实现的，通过离散的数据点构成分形插值函数，证明分形插值函数是这个IFS唯一吸引子。利用MATLAB矩阵运算，实现数据点的分形差值拟合。该算法简介直观。(The fractal difference function is implemented by the IFS fractal interpolation function through the data points of the discrete prove fractal interpolation function only attractor of the IFS. Fractal difference fitting using MATLAB matrix operations, the data points. The algorithms Profile intuitive.)
