基于PCM2902E的DRM接收前端设计
Design of DRM Receiver Front-End Based on PCM2902E
摘要
Abstract
The front-end module of DRM receiver system based on software radio technology is designed. The design can convert the analog audio signal from RF module to digital signal by AD9220 and send the digital signal from AD converter to FPGA. The digital signal is extracted to 48 kHz IF signal after digital down converter and filtering. Finally, the signal is packaged as S/PDIF frame which sent to PC through the USB sound card chip PCM2902E. The DRM receiver software on PC demodulate DRM digital baseband signal and verify the correctness of algorithm and circuit design.关键词
