Impact of Hardware Imperfections and Imperfect Channel Knowledge on SVD-precoded MIMO

This paper presents the simulation analysis of sensitivity of Singular Value Decomposition - precoded MIMO on the direct conversion front-end impairments. Besides the major impairments such as the quadrature modulator gain and phase mismatch, or the power amplifier nonlinearity, we also consider the effect of the channel estimation error. Finally, the case of aggregated impairments and estimation error is also considered.
