摘要：
In this study, we present efficient detection and precoding algorithms for massive multi-user multiple-input multiple-output wireless system. To reduce the computational complexity due to large matrix inversion, the proposed algorithms are an enhanced version of zero forcing scheme based on QR matrix decomposition for both uplink and downlink systems. Through extensive numerical experiments, we demonstrate that the proposed algorithms outperform the recently published ones in terms of performance and complexity.
