Digital sampling and digital downconversion technology is an important part of research on software radio receiver. Which for a variety of sampling rate of the signal, the signal symbol rate variable and fixed system for real-time sampling rate matching problem is one of the difficult problems in research of multi-rate signal is digitized encountered. Inserted in the text of a combination of technology solves this problem by extracting and inside. And on this basis, focuses on the high-speed decimation filter structure and a number of interpolation, laid the foundation for the rapid match the data rate.
