Popis: Recent work has shown the full duplex transmission scheme to allow nodes to send and receive in the same frequency at the same time. In this paper, we investigate the impact of analog cancellation error on the bit error rate (BER) performance of full duplex wireless communication system. Considering the transmission delay error, amplitude error and phase error of analog cancellation, we derive the analytic BER expression of binary phase shift keying (BPSK) in additive white Gaussian noise (AWGN) channel. The analysis results show that BER generally decreases with timing and amplitude error decreases for fixed signal to interference rate (SIR). Compared with the ideal analog cancellation system, the performance loss 0.3dB when the phase error is 0.0001 degree, carrier frequency is 800MHz and SIR is 100dB.
