On the Impact of the Number of Interferers and Channel Estimation Errors in SC-FDE SIMO IB-DFE Systems

Abstract

In this work, we analyze the effect of channel estimation errors on the bit error rate (BER) of a novel linear frequency domain iterative equalizer for SIMO single carrier systems with frequency domain equalization under the effect of multiple interferences, which takes the channel estimation errors into account in the equalization. It was found out that the proposed equalizer outperforms the iterative structure which does not take into account the channel estimation error process. Simulation results showed that this equalizer presents a better error performance when compared to its conventional version.
