摘要
该文应用多速率信号处理理论,对基于多相滤波器信道化接收机的数学模型进行了分析和讨论,并与传统的低通滤波法进行了比较,结果表明该方法能以较低的运算复杂度更好的实现信号的实时处理。文章最后用仿真实验结果验证了该方法的正确性。
The mathematical model of channelized receiver based on polyphase filters is analyzed and discussed by using multi--rate signal processing theory. Result of comparing it with traditional lowpass filters indicates that this method can be used to implement real--time signal processing better with a less computing complexity. Finally, a simulation result verifies the validity of this method.
