Abstract
The performance of OFDM based systems is seriously affected by imperfections in system implementation. To gain a beter understanding of the influence of these impairments on the performance of multiple antenna OFDM systems, this paper studies a zero-forcing based MIMO OFDM system with imperfections modeled as additive error sources in both transmitter (TX) and
receiver (RX). Based on this model, expressions are derived for the probability of error of uncoded impaired MIMO systems in fading and non-fading environments. These results allow for insightful
comparison between the influence of TX and RX impairments. It is concluded that the influence of RX imperfections decreases with an increasing number of RX branches, while this is not the case for TX deficiencies.
