Using random matrix theory, we derive the limiting SIR performance of a suboptimal MMSE receiver when applied to large MIMO systems with unequally-powered users. It has been proven that the limiting SIR converges to a deterministic value when K and N go to infinity with K/N = y being a constant, where K is the number of transmit antennas and N is the number of receive antennas. The limiting SIR result is then used to quantify the SIR loss for different MMSE receivers applied to MIMO systems with non-constant modulus modulations. Numerical results have shown that loss in limiting SIR is small for the suboptimal receiver as compared to optimal receiver. © 2005 IEEE.||Source Title:||2005 Fifth International Conference on Information, Communications and Signal Processing||URI:||http://scholarbank.nus.edu.sg/handle/10635/105474||ISBN:||0780392833|
