信道主要模拟信号的多径传输，在这个信道中一共有三个用户的数据进行传输，用户一经过了2径衰落，用户二经过了3径衰落，用户三经过了4径衰落。(The main channel simulation of multipath signal transmission, in this channel has a total of three users of the data transmission, the user after 2 path fading, the user of two after 3 path fading, the user of three after 4 path fading. )

级联积分－梳状(Cascaded Integrator–Comb，CIC)滤波器，是种高 效滤波器。它是一种线形相位FIR滤波器，由工作在高抽样率的级联理 想积分器和低抽样率的级联微分器组成,根据抗混叠和抗镜像的指标 确定所需的级联数目。 (Cascaded integrator- comb (Cascaded Integrator-Comb, CIC) filter, is the kind of high efficiency filter. It is a linear phase FIR filter, high sampling rate by the work in the cascade of an ideal integrator and a low sampling rate of the cascade differentiator formed, according to anti-aliasing and anti-mirror of the indicators to determine the number of required cascade.)
