| Abstract: | In view of demanding a regular intermediate frequency spectrum analysis in satellite communication system,a intermediate frequency direct sampling and digital signal processing method is put forward.Poly-phase filtering and channel dividing optimizing method are adopted in the design,the bottleneck of over-fast in data rate is overcome,and the design is best simplified and the cost is mostly reduced. |
