Abstract

One of the key challenges to enable high data rates in the downlink of LTE-Advanced (LTE-A) is the precoding and receiver design. In this work, we focus primarily on the UE and the base station (BS) processing, particularly on estimating and using the interference resulting from strong neighboring stations. In this paper, we propose a novel receiver design that performs well in the presence of interference. Furthermore, we present a precoding scheme that the BS can use to maximize the signal-to-interference plus noise-ratio (SINR). The proposed algorithm performs well under high speed channels. The limitations of the Minimum Mean Square Error (MMSE) receiver have been discussed and it was used for comparison purposes with the proposed approach. Finally, an interference free scenario is used as a benchmark to evaluate the proposed system performance.
