A Multimode Receiver Based on Software Radio Design
YE Yong-ping · Journal of Hangzhou Dianzi University · 2012
The software radio receiver is based on a general programmable hardware platform and realizes all kinds of corresponding standards through software.With the development of the digital processing technology,the ideal software radio becomes into a reality.This paper discusses some issues such as the key technologies,the system architecture,the radio-frequency signal processing,the intermediate frequency signal A/D processing technology,the digital signal multi-schema processing,the digital demodulation,the software radio receiver.And also,it takes AM,SSB,CW,the FM signal as examples to simulate the design proposal to validate its feasibility.
