Introduction Matlab is an ideal tool for simulating digital communications systems, thanks to its easy scripting language and excellent data visualization capabilities. One of the most frequent simulation tasks in the field of digital communications is bit-error- rate testing of modems. The bit-error-rate performance of a receiver is a figure of merit that allows different designs to be compared in a fair manner. Performing bit-error-rate testing withMatlab is very simple, but does require some prerequisite knowledge.

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.)
