Interference aware iterative receiver performance for the uplink of LTE-A

Abstract

In this paper we study the performance of an interference aware iterative block decision feedback equalizer (IBDFE) for the uplink of LTE-Advanced with single carrier (SC) transmissions. The receiver makes use of the correlation between the interference in the receiving antennas and minimizes the mean squared error (MMSE) of the detected symbols. Link level simulation results show that the proposed receiver clearly outperforms the conventional IBDFE and the linear interference rejection combining (IRC) detector. System level simulation results show that the use of the new iterative receiver achieves additional throughput gains. However, the gains obtained depend on the schedulers employed and on the number of receiving antennas.
