摘要：
This paper focuses on the RFI signal in the impulse UWB system with equivalent time sampling. RFI signals in the equivalent time sampling cannot be completely recovered. To reveal the properties of the aliased RFI signals, we setup a simple mode of the RFI signal with time-varying phase and analyze the effect of the classical average operation. Simulations about the random and periodic equivalent time sampling schemes are performed and compared, and indicate that the RFI suppression has more relationship with the average factor other than the random equivalent time sampling scheme.
