Abstract :
The second-order statistics of the time varying signal to noise ratio at the output of a multiple-input-multiple-output(MIMO) system with maximal ratio combining (MRC) are analyzed. Exact closed-form expressions for the level crossing rate and the average fade duration are derived for the Ricean propagation and arbitrary channel matrix dimensions. Novel expressions are compared with the special case of MRC receive diversity. The analytical results are validated by simulation.
