Abstract

A very low complexity power allocation strategy for MIMO systems with channel estimation error and channel covariance feedback is proposed. By maximising the Jensen bound on the average mutual information and using its optimiser to approximate the optimal input covariance, the strategy needs only a fraction of computational effort compared to the optimal strategy and achieves suboptimal performance.
