DES3200实验系统的模拟信号输出通道产生一个1KHz 的方波,然后利用信号输入通道对产生的方进行低通滤波,得到一个1KHz 的正弦信号，并使用CCS 的图形显示工具显示输入和输出的波形。这里我们使用的是一个46阶的对称结构的FIR低通滤波器，其采样频率Fs为25KHZ，通带截止频率 1KHZ，阻带截止频率为3KHZ，阻带衰减为-60dB。(DES3200 experimental system analog output channel generates a 1KHz square wave, and then use the signal input channels that produce low-pass filtering the square to get a 1KHz sinusoidal signal, and use the CCS' s graphical display tool shows the input and output waveforms. Here we use a symmetrical structure of 46-order FIR low-pass filter, the sampling frequency Fs to 25KHZ, passband cutoff frequency 1KHZ, stopband cutoff frequency 3KHZ, stop-band attenuation is-60dB.)

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.
