Abstract
We study the capacity of a single-user channel with multiple antennas and limited feedback. The receiver has perfect channel knowledge, and can relay B bits, which specify a beamforming vector, to the transmitter. We show that a Random Vector Quantization scheme is asymptotically optimal, and give a simple expression for the associated capacity.
