基于多相滤波器的信道化接收机及其应用研究

The realization of channelized receivers based on polyphase filters

本文主要研究了应用多相滤波技术的信道化接收机建模问题。在给定信道频谱划分方案下,推导了基于多相 滤波器的信道化接收机数学模型。并由此模型设计了一个四信道模拟系统。最后用仿真实验结果验证了模型的正确性。

In this paper, the problem of how to realize a multi-channel receiver is discussed in details. First, under a channel spectrum partition given, a mathematical model of channelized receivers is derived, based on polyphase filters. Then, a simulation system of realizing four channels receivers, from the model, is designed. All the experimental results show that our model is valid and practical.
