摘要
中频数字化是软件无线电(SDR)系统设计中的一项关键技术。从射频、基带与中频的制约关系出发,结合Graychip公司生产的多通道数字下变频器GC4016芯片,给出了中频数字滤波器的设计方法,从理论上进行了分析和仿真,并在实际工程中进行了实验验证,得到了预期的结果。
IF（ intermediate frequency）digitalization is a critical technology in software defined radio（SDR） system design. Based on multi - channel DDC-GC4016 chip produced by Graychip Inc. , a design method for IF digital multi -rate filters is presented according to the relationship between RF, baseband and IF. Then analysis is made and simulation is performed. Finally ,this method is validated in project and the desired purpose is achieved.
