Improving the reliability of receivers for 5G networks

Abstract

Multiple-input multiple-output (MIMO) systems with a large number of antennas are imperative for future wireless networks. The reliability of receivers in such networks depends critically on the detection algorithm used. The existing detection algorithms for such systems can be grouped into three categories viz. neighborhood search algorithms, lattice reduction based algorithms and sparse recovery based algorithms. Although these algorithms have reasonably low complexities, their reliability performance needs further improvement. In this paper we propose a novel structure for realizing significantly improved error performances by using existing algorithms as tools.
