Abstract A lowcomplexity user selection algorithm was proposed for multicell multipleinput multipleoutput (MIMO) system employing orthogonal spacedivision multiplexing (OSDM) with outofcooperativecells interference suppression. The algorithm iteratively selects users through greedy search. In each user selection step, the user who contributes most to the average cell capacity is added to the selected user set, and the number of activated users is adaptively adjusted to maximize the average cell capacity. The simulation results show that compared with the user selection algorithm in MIMO system employing block diagonalization (BD) with outofcooperativecells interference suppression, the algorithm proposed can achieve higher average cell capacity, and support more users with the same signaltonoise raitio (SNR) and interferencetonoise raitio (INR).
