In this paper, the effects of oscillator phase noise (PN) with arbitrary spectral characteristics on the self-interference (SI) cancelation capability of a full-duplex radio (FDR) transceiver are addressed, and design considerations for optimized phase-locked loop (PLL) design in FDR are given. This paper first presents a full-duplex transceiver model that inherently mitigates most of the phase-noise effects from the SI signal. The remaining effect of the PN is then analyzed, and closed-form expressions for the SI power are derived. In the simulations part, a practical PLL-type oscillator is used, which is based on the arbitrary mask phase-noise model. Analytical derivations are verified with the simulations, and the SI cancelation performance is thoroughly studied with various parameters. Design considerations are finally given for oscillator design in FDR transceivers, with the help of tangible parameters of the PLL-type oscillators. [ABSTRACT FROM AUTHOR]
