Antenna Grouping과 Beamforming 사이의 Transmit Mode Selection 기법

Antenna grouping is better than beamforming regarding BER performance in MIMO IID channel. But as channel correlation gets larger, the average BER performance of antenna grouping is degraded and worse than beamforming's. We propose a robust mode selection technique between antenna grouping and beamforming and its criterion. Using curve fitting, this technique is very simple. BER performance of proposed algorithm is also better than antenna grouping and beamforming irrespective of channel correlation.
