衰落信道仿真 function r = rayleigh( fd, fs, Ns ) r = rayleigh(fd,fs,N) A Rayleigh fading simulator based on Clarke s Model Creates a Rayleigh random process with PSD determined by the vehicle s speed. INPUTS: fd = doppler frequency set fd = v*cos(theta)/lambda v = velocity (meters per second) lambda = carrier wavelength (meters) theta = angle w/ respect to tangent (radians). fs = sample frequency (Samples per second) Ns = number of samples of the Rayleigh fading process to produce OUTPUTS: r = row vector containing Ns samples of the Rayleigh fading process Author: Matthew C.

这是用于目标跟踪的粒子滤波代码， 用matlab编写的，很有借鉴性，一维情况下， 非高斯非线性，其中将扩展卡尔曼滤波与粒子滤波进行比较，更好的说明了粒子滤波的优越性(This is a particle filter for target tracking code using matlab, referential nature, one-dimensional case, the non-Gaussian non-linear, which will be extended Kalman filter and particle filter to compare, a better description of the particle the superiority of the filter)

he increasing demand of networks, over the past decade has led to the need for enormous cost reduction and increasing accessibility of networks. It requires for efficient traffic management in the network and ability to expand as per the need. Various network design problem solutions are based on enumerative and heuristic approach have been defined in the literature.
