摘要
Abstract
On the basis of the theories of digital down⁃conversion(DDC)and digital up⁃conversion(DUC),a high⁃perfor⁃mance digital intermediate frequency (IF) transceiver is proposed,which takes FPGA+DSP as the core. The implementation theories of direct DDC and DUC are expounded,and the design method and filtering coefficient of the delayed correcting filter are put forward. And then the implementation methods of ADC sampling circuit,FPGA design logic of DDC/DUC,DSP data read⁃write and processing flow,DAC conversion circuit and filtering circuit are discussed. The actual system was tested with loopback mode. The test results prove that the system has good real⁃time performance.关键词
