Abstract

An analytical method for the performance evaluation of adaptive multiple-input-multiple-output (MIMO) system employing maximal ratio combining (MRC) by a Markov model is developed. The finite state Markov channel model parameters were determined by a new exact expression for level crossing rate of the signal to noise ratio at the output of MIMO-MRC with imperfect channel state information, derived for the Rayleigh propagation and arbitrary channel matrix dimensions. The analytical results are validated by computer simulation.
