| Abstract: | For the low power consumption and digital demand of satellite communication equipment,a design of low power digital satellite modulation-demodulation platform is proposed.The front end uses AD9364 to complete the transformation between analog signal and digital signal,and the back end adopts large-scale FPGA to perform digital signal processing.The test result shows that,by loading different software,the design of the modulation-demodulation platform can realize variable data rate,variable modulation and demodulation mode,expanded L band,and greatly reduce the platform size and power consumption,which can be used as a mature platform for the design of satellite communication terminal or portable station products. |
