In this work, we analyzed the performance of SM-MIMO CR system under the effect of hardware and channel impairments. In addition, a closed-form expression for the APEP and a general tight upper bound of the ABER were derived to study the effect of those key parameters on the secondary system performance. Moreover, simple approximate error expressions were obtained at high SNR values, from which we got the diversity order of the system. Obtained results reveal that error system performance deteriorates in the presence of such effect and performance saturates to a constant value.

N2 - In this work, the performance of spatial modulation (SM) for multiple-input multiple output (MIMO) underlay cognitive radio systems is studied under the effect of channel and hardware impairments. Specifically, a closed-form expression of the average pairwise error probability (APEP), an asymptotic APEP, and a tight upper bound of the average bit error rate (ABER) are derived for Rayleigh fading channels. Useful remarks are highlighted on the system diversity and on the impact of channel and hardware impairments. Numerical results, which are corroborated through simulations, show that the ABER performance saturates to a constant value in the high power region due to the effects of channel and hardware impairments.
