A Scheme for Self-interference Cancellation with Phase Noise in Full-duplex
The phase noise caused by oscillator is an important factor that limits the self-interference cancellation performance.In this paper, a digital self-interference with phase noise cancellation scheme for full-duplex OFDM systems is proposed.The proposed scheme has two main steps: an estimation phase and a cancellation phase.The first step is based on the frequency domain estimation and time domain interpolation.In the second step, the estimated coefficient is used to suppress the self-interference with phase noise.Finally, we numerically investigate the performance of the proposed scheme, and the results show that the proposed scheme could achieve up to 12dB more self-interference cancellation gain than the existing digital domain cancellation scheme.
