AbstractThe content of this paper is putting forward an idea that applies the software radio technique to the subcarrier demodulation of frequency divided multiplexing telemetry system. Firstly, the article explains the basic thought and application of the software radio. It introduces the main function and the use of the programmable downconverter in HSP50214/ HSP50216. Secondly, it discusses the merit and shortcoming about the method of the subcarrier demodulation of frequency divided multiplexing telemetry system in common use. Finally, the article aims at ± 7.5% proportion bandwidth FM subcarrier channels that in common use in the military standard, introducing HSP50214/HSP50216 programmable downconverter in achievement of design and simulation result. The main problems in the design are discussed and a conclusion obtained.
