| Abstract: | This paper presents a design of an intermediate frequency(IF)multi-demodulator based on a software-defined radio system incorporating a field-programmable gate Array(FPGA).The mathematical structures of the demodulations,the realization of the program based on FPGA and analysis of the test results are described.The system is based on a common hardware platform and modular software design which results in a considerable saving in hardware resources whilst achieving nine kinds of demodulation mode.The results of actual simulations and tests meet the design requirements for stability and reliability. |
