In order to decrease the mirror frequency interference, cross interference and inter-modulation interference, double IF (Intermediate frequency) is adopted in the receiver.
为了降低镜频干扰、交调和互调干扰，接收机采用了双中频方案。

This function is used to forward link IS-95 system simulation, including the expansion of frequencymodulation, matched filter, RAKE receiver, and other related communication module.
此函数用于IS - 95前向链路系统的仿真，包括扩频调制，匹配滤波，RAKE接收等相关通信模块。

In the receiver, through the appropriate RC or LC network can filter out square wave and high frequencymodulation signal for simulating the reduction form.
