This paper investigates the error performance variation of block-type time-domain equalizers in MIMO systems according to frequency selectivity of the frequency-selective channel. We consider the linear time-domain equalizers and the non-linear decision-feedback equalizers, and the error performance of the time-domain equalizers is investigated according to the number of channel taps via numerical simulations. Simulation results show that both types of time-domain equalizers obtain error performance improvements as the number of channel taps increases, while the SNR improvement by the increased number of channel taps is more significant for the non-linear equalizers. Therefore, although the increased frequency selectivity requires the increased receiver complexity, the error performance of the time-domain equalizers in MIMO systems can also be improved with the frequency selectivity.
