摘要
目前的无线电正朝着软件无线电方向发展,因此如何用实现高速射频采样数据下变频到低速基带就成了一个关键问题。本文在简要介绍软件无线电的基础上,提出了利用多速率信号处理和高效数字抽取滤波器的几种实现方法。
Now the radio system is developing towards software radio.So how to realize the conversion of high speed RF sampling data down to low speed base band data becomes a key problem.On the basis of the introduction of software radio,this paper puts forward design schemes to use multirate signal processing and efficient digital decimate filter to downconvert,then analyzes and compares them.
