MSE of ChebI-NS, NI-NS, SOR-AMI, ChebI-SOR-AMI, and NI-SOR-AMI methods versus number of BS antennas (N) for uncorrelated channel at the second, third, and fourth iterations, respectively. This figure computes the MSE of four approximate matrix inversion techniques for uncorrelated channel conditions under second, third, and fourth iterations, respectively. a iteration, i=2. b iteration, i=3. c iteration, i=4
