In this paper, We proposed the Interference Canceller System(ICS) for the CDMA RF repeater in order to remove the feedback signals. By combining the proposed ICS, we can improve the isolation between the transmitting antenna and the receiving antenna in the RF repeater. So, the distance between the transmitting antenna and the receiving antenna can be reduced to 3∼4 m. We have simulated the proposed ICS, and the simulation results show that the isolation can be improved by 30dB.
