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 calculating time and hardware resource can be saved.Matlab simulation shows that the method is practicable and feasible,it can be used for a multi-rate processing system of a digital receiver.
