An Efficient Signal Detection Algorithm for 3GPP LTE Downlink

Abstract

In this paper, we investigate an efficient signal detection algorithm, which combines lattice reduction (LR) and list decoding (LD) techniques for the 3rd generation long term evolution (LTE) downlink systems. The resulting detector, called LRLD based detector, is carried out within the framework of successive interference cancellation (SIC), which takes full advantages of the reliable LR detection. Simulation results show that the proposed LRLD based detector provides a near maximum likelihood (ML) performance with a significantly reduced complexity.
