摘要： 本文在宽带数字信道化接收机通常采用多相滤波器组结构和STFT结构方法实现信道化的基础上，推导了利用多相STFT结构实现信道化接收的方法。多相STFT结构将多相结构与STFT结构结合起来，利用多相结构降低数据处理速率，采用STFT实现信道化。采用该方法实现数字信道化时，接收机时频分辨能力强，占用硬件资源少，非常适用于信道数较多的数字信道化接收机的设计。

Abstract： In this paper, based on the channelized method of polyphase filter bank structure and STFT structure that wideband digital channelized receiver usually adopts, multiphase STFT structure is deduced. Multiphase STFT structure combines multiphase structure and STFT structure together, uses multiphase structure to reduce the data rate and STFT structure to realize channelization. Digital channelized receiver has good time-frequency resolution ability, occupies less hardware resources when the channelized method of multiphase STFT structure is used. The method is very suitable for the digital channelized receiver which has a large number of channels.
