However, they do not account for any interference scenarios. Smart antennas are divided into two groups: - Phased array systems (switched beamforming) with a finite number of fixed predefined patterns. Conventional Beamforming Uses for Beamformers. Y = step(H,X) performs LCMV beamforming on the input, X, and returns the beamformed output in Y. Quantized feedback in multiple antenna systems has potential to increase throughput and/or reduce probability of outage.
