Abstract

This work investigates a design of minimizing the system outage probability adaptive modulation algorithm in the downlink of the multi-user multiple-input multiple-output (MIMO) system. Based on a beamforming scheme that maximizes the signal-to-leakage ratio (SLR), this new algorithm is proposed for constant bit rate services to maximize the number of satisfied users and minimize the transmission power. Furthermore, this proposed algorithm has advantage in the system spectral efficiency.
