用Rayleigh-Normal模型仿真对数正态信道模型(Model simulation with Rayleigh-Normal lognormal channel model)

基于OFDM无线信道特性建模与仿真,这是一篇很好的解释，OFDM信道模型建立的论文，对于这方面的仿真有很大的参考意义。(OFDM-based wireless channel modeling and simulation, this is a good explanation, OFDM channel model of the paper, the simulation for this great reference value.)

说明：  设计一个巴特沃兹数字低通滤波器，其技术指标为：3dB带宽为0.2π，阻带截止频率为0.3π，通带纹波为1dB，阻带衰减大于30dB，采样间隔T=10ms。 1）采用冲激响应不变法； 2）采用双线性变换法设计； 3）采用FIR的窗函数（Hanning窗、Hamming窗或Blackman窗）设计。(A Butterworth digital low-pass filter is designed. Its technical specifications are: 3 dB bandwidth is 0.2 pi, stopband cut-off frequency is 0.3 pi, passband ripple is 1 dB, stopband attenuation is more than 30 dB, sampling interval T=10 Ms. 1) Impulse response invariance method is adopted. 2) Design by bilinear transformation method; 3) FIR window function (Hanning window, Hamming window or Blackman window) is used to design.)

用KALMAN滤波程序写的对于运动过程的仿真 采用了采用蒙特卡洛方法对跟踪滤波器进行仿真分析,(Monte Carlo method is used to simulate the tracking filter, which is written by KALMAN filter program.)
