Abstract
We propose a design of minimizing transmission power adaptive modulation (AM) that utilizes imperfect channel state information (I-CSI) in multi-input and multi-output (MIMO) systems. By taking channel estimation errors into account, the proposed algorithm provides the quality of services (QoS) closed to the expected values when larger channel estimation error occurs. Furthermore, we, make comparison between the proposed algorithm and the ideal one based on perfect CSI assumption, and present the simulations results to illustrate the performance advantages at last
