Description/Abstract

Abstract: Energy efficiency is a primary design goal for future green wireless communication technologies. Multiple-input multiple-output (MIMO) schemes have been proposed in literature to improve the throughput of communication systems, they are expected to play a prominent role in the upcoming 5th generation (5G) standard. This paper presents a novel high efficiency MIMO decoder based on the K-Best algorithm with lattice reduction. We have designed a novel hardware architecture for this decoder, which was implemented using 32nm standard CMOS technology. Our results show that the proposed decoder can achieve on average a four-fold reduction in the power costs compared to recently published designs for 5G networks. The throughput of the design is 506 Mbits/sec, which is comparable to existing designs.
