In this paper, the performance of a proposed antenna selection algorithm is evaluated that is based on cooperative interference mitigation among neighbouring base stations. This algorithm has been evaluated in MIMO - OFDMA cellular networks, for various bit rates per mobile user and blocking probabilities. As preliminary results indicate, for 64QAM modulation type and 2/3/4/5 allocated subcarriers per mobile user, the proposed antenna selection approach can provide up to 14%/50%/36%/25% gain on the mean number of active users in the network compared to the case where antenna selection is performed having as sole criterion the maximization of Signal to Noise Ratio.
