Level Crossing Rates of Ricean MIMO Channel Eigenvalues for Imperfect and Outdated CSI

In this paper, the exact closed-form expressions for the level crossing rates of the multiple-input multiple output (MIMO) channel ordered eigenvalues are derived for the Ricean propagation and arbitrary channel matrix dimensions. The novel expressions can be applied for the imperfect channel state information (CSI) and feedback delay, with or without prediction. The analytical results are validated by simulation.
