Abstract
In this paper, the effective capacity of multiple-input multiple-output (MIMO) maximal ratio combining (MRC) system is studied. By considering constant power loading, a closed-form expression for the effective capacity is derived. While for variable power loading, restricted by the average power, optimal power loading scheme and associated effective capacity is given. Adaptive modulation is used for both constant and variable power loading, and the superiority of variable power loading versus constant power loading is demonstrated by the computer simulations.
