Capacity Analysis of Lattice reduction Aided Detection in Massive-MIMO systems

Abstract

With the growing demand of future communication system, massive MIMO become a hot research topic. And Lattice reduction (LLR)-aided equalizers have been well researched for multi-input multi-output (MIMO) systems due to its bit-error-rate (BER) improvement over linear equalizers (LEs) and with relatively low complexity. This paper deal with the analysis of the channel capacity in massive MIMO system. Here, the performance of the LLR aided ZF and MMSE receives have been demonstrated along with the comparison between the linear receivers. The detail mathematical calculation for the improvement inn channel capacity due to LLR aided receiver over the linear receiver has been presented and verified through the simulated results.
