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。(This program is the simulation process of channelization technology in software radio. It uses a "polyphase filter structure" to modulate 32 frequency components. The average modulation is in the spectrum, which improves the spectrum utilization of the transmitted signal. The program is helpful for understanding channelization and polyphase filtering.)
