Bit-error-rate minimisation in multiuser transmission schemes for multiple-input–multiple-output communication with increasing number of base station antennas


Multiuser transmission (MuT) can be carried out at the base station of a multiple-input-multiple-output system for mitigating the downlink multiuser interference, achieving a close to-single-user performance at the mobile terminals. These MuT systems will be designed for optimising completely different performance metrics, like the bit-error-rate (BER), that is the main focus of this study. In order to mitigate the MuT's complexity, a convex formulation for the minimum BER (MinBER) optimisation problem is proposed, by employing some slight modifications on its original formulation. The authors have shown that the novel convex formulation makes the application of some optimisation algorithms terribly economical, resulting in a reduced complexity and enabling the system operation in higher dimensions. Indeed, the authors additionally show that in these conditions the MinBER-MuT system presents the most noticeable gains in performance. The results demonstrate that, among the investigated techniques, the proposed Line Search Quasi-Newton algorithm looking forward to the penalty operate approach results in the simplest performance versus complexity trade-off within the context of high capacity multiuser systems.
