“…As described in [7, 8], the complexity of finding the optimal subset of antennas to maximise the capacity or minimise the bit error rate (BER) grows exponentially with the number of available antennas. Thus, lower‐complexity capacity‐maximising antenna selection methods were pursued to achieve the near‐optimal performance with reduced complexity [9–11]. In addition, previous literatures on antenna selection mainly focused on the case where the number of available antennas was fixed.…”
