%X Polyphase based digital downconvertion is widely used in software electronic system design because it is easy to be realized and also has anti-jamming ability. But this method has blind frequency zone. This paper proposes a new method based on polyphase digital downconvertion which can eliminate the blind frequency zone and realize the receiving of any IF bandpass signal without changing the structure.
