N2 - This paper presents a strategy to allocate power both in space and time for beamforming orthogonal space-time block coded multiantenna systems with imperfect channel state information at the transmitter. Most of the existing schemes focus on spatial-only power allocation, while the temporal dimension is not well exploited. The proposed space-time strategy is developed by decoupling the temporal and spatial power calculation through asymptotic analysis, resulting in efficient computation. Numerical results demonstrate that the proposed scheme has considerable performance gains over the existing power adaptation schemes. © 2011 IEEE.
