This paper reports the performance of Block Diagonalization (BD) scheme for different array antenna structures used in a multiuser Multiple Input Multiple Output (MIMO) system. The assessment is performed in terms of sum rate capacity. Theoretical analysis as well as computer simulations shows that the spatial correlation downgrades downlink performance of BD. The simulations also reveal that the...
This paper is concerned with the optimal transmission/power allocation scheme for a MIMO system employing a uniform circular array (UCA) antenna at the transmitter and a uniform linear array (ULA) antenna at the receiver. Investigations include mutual coupling (MC) effects in the UCA. By applying the transmitting mutual impedances, closed-form expressions for the spatial fading correlation (SFC) function...
