Hardware Implementation of the Efficient SOR-Based Massive MIMO Detection for Uplink

Abstract

In Massive MIMO's uplink, the signal detection algorithms such as minimum mean square error (MMSE), zero-forcing (ZF) achieve nearly optimal result, but they use inverse matrix in design, the complexity in calculation is very large. In this paper, we propose an efficient algorithm based on the SOR (Successive over Relaxation) algorithm with the better performance than the conventional SOR-based algorithm. The obtained result shows that the performance of the efficient SOR-based algorithm is better than the conventional SOR-based algorithm and close to MMSE algorithm. Besides, we propose the hardware architecture for the proposed SOR-hased algorithm.
