BER performance comparison between SSOR, NI-SOR-AMI, and ChebI-SOR-AMI method N×K=256×32 mMIMO system for uncorrelated and correlated channel conditions. This figure compares SOR-AMI, ChebI-SOR-AMI, and NI-SOR-AMI with conventional SOR and SSOR methods under correlated and uncorrelated channel conditions for the second and fourth iterations. a Uncorrelated channel, i=2. b Uncorrelated channel, i=4. c Correlated channel, i=2. d Correlated channel, i=4
