中文说明：
该程序是软件无线电中信道化技术的仿真历程，使用了“多相滤波结构”，将32个频率分量进行调制，平均调制在频谱之中，提升了发射信号的频谱利用率。该程序有利于对信道化与多相滤波的理解。
English Description：
The program is channelized technology of software radio in the simulation process, use the "polyphase filtering structure", will be 32 modulation frequency component, average modulation in the spectrum, improve the spectrum utilization of transmitting.The program is helpful to the understanding of channelized and polyphase filtering.
