摘要：

This letter proposes a self-interference (SI) suppression method for in-band full duplex relaying. SI is suppressed by using a feedforward linear FIR filter which is adaptively adjusted in a blind manner. Simulation results show that the proposed method can suppress SI successfully and is less sensitive to transceiver hardware imperfections than the conventional SI cancellation methods using feedback filters.
