BER performance comparison between different joint NS methods with ChebI-NS method in mMIMO system with N=128 and K=16 under uncorrelated and correlated channel, respectively. This figure compares ChebI-NS with other previous NS methods for iterations i = 2, 3, 4 under both correlated and uncorrelated channel conditions. a Uncorrelated channel, i=2. b Uncorrelated channel, i=3. c Uncorrelated channel, i=4. d Correlated channel, i=2. e Correlated channel, i=3. f Correlated channel, i=4
