软件无线电接收机多速率信号的多段处理方法研究

在软件无线电数字接收机中，为了支持多种速率的信号处理，通常采用分数倍重采样，在硬件实现时，非常耗时和耗资源，这也成为软件无线电数字接收机的难点。在分析传统实现模型的基础上，提出一种基于整数倍重采样的新方法，即按照一定的分段方法，实现多速率的多段动态处理，可以避免分数倍重采样，节省运算时间和硬件资源。通过Matlab仿真证明，该方法性能良好，实用可行，可以用于数字接收机的多速率处理系统，在其工程实现上有较大的参考意义。

Research on Multi-stage Multi-rate Processing for SDR Receiver

Generally,non-integer re-sampling is used in a digital software radio receiver to support multi-rate signal processing,and it is very time-consuming and resource-consuming when implementing the hardware,which has also become a difficulty for the digital software radio receiver.On the basis of a traditional implementation model,a new implementation method,to realize multi-rate multi-stage processing according to a certain segmenting method is proposed,thus non-integer re-sampling can be avoided,the calculati...
