Abstract
Hardware impairments (HI) due to imperfect manufactured electronic parts degrade the performance of wireless systems. In this paper, we consider a bidirectional full-duplex (FD) spatial modulation (SM) multiple-input multiple-output (MIMO) system with non-ideal hardware and residual self-interference (RSI). We propose to use the transmission antenna selection (TAS) as a solution to mitigate this degradation. The performance of the considered system is analyzed using mathematical analysis. Specifically, we first derive the exact closed-form expressions of the outage probability (OP), symbol error probability (SEP), and achievable data rate (ADR) for two cases: with and without TAS. Given these expressions, we conduct a detailed evaluation of the system performance under various scenarios to gain insight into its behavior. Essential conclusions are then made on HI and RSI’s impacts, especially for the case with TAS and high transmission rates.

N OWADAYS, the need for Internet-of-Things (IoT) devices has increased very fast to provide users with anytime and anywhere connection to the Internet [1], [2]
We propose to use transmission antenna selection (TAS) as an effective solution to compensate for the joint impact of both Hardware impairments (HI) and residual selfinterference (RSI) in a point-to-point FD-spatial modulation (SM)-multiple-input multiple-output (MIMO) system over the Rayleigh fading channel
As we are interested in analyzing the impact of both HI and RSI as well as the effect of the TAS scheme on the system performance, we assume that the receivers of both A and B can perfectly estimate the activated antenna indices of respective transmitters for the maximum likelihood (ML) detection
Summary
N OWADAYS, the need for Internet-of-Things (IoT) devices has increased very fast to provide users with anytime and anywhere connection to the Internet [1], [2]. The subsequent works in [15], [16] evaluated the performance of the FDSM-MIMO cooperative systems with FD-SM relays They have derived the upper-bound BER for the case with energy harvesting (EH) at the FD relay [16] and the OP for the cascaded α − μ fading channel [15]. The OP, SEP, and ADR of SM-MIMO system with perfect hardware and perfect SIC can be derived This is the first work obtaining three mathematical expressions (OP, SEP, and ADR) of the SM-MIMO system under the joint and cross effects of HI and RSI in the cases with and without TAS.
