Abstract
We determine a necessary and sufficient condition under which beamforming (scalar coding) achieves Shannon capacity in a narrowband point to point communication system employing multiple transmit antennas and a single receive antenna. We assume perfect channel state information at the receiver (CSIR) and either channel mean or channel covariance feedback from the receiver to the transmitter. We find that better feedback quality not only increases the system capacity but also reduces the required decoding complexity at the receiver.
