This paper presents a strategy for allocating power in both space and time for beamforming space-time-coded multiantenna systems with imperfect channel state information at the transmitter (CSIT) over flat and quasi-static Rayleigh fading channels. We first develop a closed-form spatial-only (S-O) power allocation scheme based on a newly defined compressed signal-to-noise ratio (CSNR) criterion. The...
