摘要

This article provides a scheme of Intermediate frequency FM Modulation And Demodulation in a multimode Software Radio Station. The author not only introduces the hardware structure but also the software arithmetic. This scheme has already been used in some wireless telecommunication equipment to transmit several kinds of signals include analog voice signal, data, numeric signal, etc. This device realizes modern wireless equipments have been widely used in various fields of national economy. Signals transmitted not only analog voice signals but also data,digit,image,etc.This oneboard hardware platform realizes the aim of Software Radio to fulfill various signals' processing through software programming. This board has many advantages, such as strong anti-jamming capability, stabilization and credibility, felicitous arithmetic, and excellent practicality.
