  This paper addresses the performance of a full-duplex (FD) generalized
frequency division multiplexing (GFDM) transceiver in the presence of radio
frequency (RF) impairments including phase noise, carrier frequency offset
(CFO) and in-phase (I) and quadrature (Q) imbalance. We study analog and
digital self-interference (SI) cancellation and develop a complementary SI
suppression method. Closed-form solutions for the residual SI power and the
desired signal power and signal-to-interference ratio (SIR) are provided.
Simulation results show that the RF impairments degrade SI cancellation and FD
GFDM is more sensitive to them compares to FD orthogonal frequency division
multiplexing (OFDM). Hence, we propose an FD GFDM receiver filter for
maximizing the SIR. Significantly, it achieves 25 dB higher SIR than FD OFDM
transceiver.
