In this paper, a full-duplex transceiver with a two-stage analog interference cancellation architecture is proposed for the prevailing wireless full-duplex communication, which enables simultaneous transmission and reception on the same frequency. This two-stage cancellation architecture jointly combines the structures of two typical analog self-interference (SI) cancellation approaches, i.e., the...
This paper presents the nonlinear effects of the analog self-interference (SI) canceller and a practical solution to suppress the nonlinear distortions in multiple-input multiple-output (MIMO) full-duplex wireless communication systems. Due to the inherent nonlinearities of the active radio frequency (RF) components used to tune the attenuations and the phase shifts in the analog SI cancellers, nonlinear...
