Research and simulation of wideband receiver based on software radio
Zhou Sheng-yuan · Electronic Design Engineering · 2010
The flexibility for software radio systems require RF front-end receiver is able to work in quite a wide frequency range.This paper presents a design scheme for wideband receiver in the software radio broadcasting stations.The nationality of three-frequency mixing method is analyzed and validated.The function of each module in the design scheme is described in detail in this paper.Then the modeling and simulation of the whole system is proceeded.The results show that this de-sign scheme has a good selectivity,IF gain and noise figure is less than 5dB.
