A MIMO approach is to transmit and receive two or in a multiple-input multiple-output environment.

By allowing for the simultaneous required for successful transmissionfor individual link transmission of multiple data streams, MIMO multiplies is evaluated from the probability density functions of wireless data capacity without using additional frequen- eigenvalue and equivalent uncoupled multiple-input cy spectrum [6], [7]. Therefore, MIMO systems play an multiple-output link. Impact of the num
