摘要：
This article introduces the inevitability of multi-rate signal processing in the application of SDR, and then describes the hardware requirements for the realization of multi-rate signal processing in SDR, as well as its development in this stage. It mainly analyses how to realize the software part of multi-rate signal processing in FPGA, and can achieve the optimal programs and methods by comparing several kinds of different schemes on the rate of transformation. At the same time,we can get the simulation map of the 1-order CIC interpolation and the 1-order CIC extraction, respectively. And then through the analysis to the interpolation and extraction of the scores of times, we will obtain the realization of the program. Finally, download the 1-order CIC interpolation and extraction to FPGA and get the realization of multi-rate signals through authentication by the logic analyzer.
