| Abstract: |
| Based on the high-speed A/D converter AD6644,the programmable digital down converter AD6620 and the high performance TMS320C6416,a platform for processing IF digital signals is established.And the hardware and software design of it are analyzed in detail.Since it is universal and flexible,the platform can be used as a perfect experiment platform for the research of software defined radio(SDR). |
| Key words: software defined radio(SDR),IF sampling,digital down converter(DDC),design |
