In this paper, a multiple-input multiple-output (MIMO) full-duplex (FD) transceiver design is proposed, which can mitigate the impact of phase noise and provide an enhanced self-interference cancellation capability. This design is featured by finely tuning the delay of the transmit oscillator signal and using it as the receive oscillator signal. To maximize the cancellation capability, a delay selection principle is developed to calculate the optimal oscillator delay. To further reduce the number of parameters needed in the delay calculation, a simplified principle is also developed with acceptable loss of cancellation capability. Compared to the traditional transceiver with a shared oscillator for its transmitter and receiver, the proposed design achieves an obvious improvement about 10 dB in terms of cancellation capability.
