Environmental issues for MIMO capacity

Wireless communication using multiple-input multiple-output (MIMO) systems enables increased spectral efficiency for a given total transmit power. Increased capacity is achieved by introducing additional spatial channels that are exploited using space–time coding. In this paper, the environmental factors that affect MIMO capacity are surveyed. These factors include channel complexity, external ...

MIMO capacity with interference

System capacity is considered for a group of interfering users employing single user detection and multiple transmit and receive antennas for at Rayleigh fading channels with independent fading coeecients for each path. The focus is on the case where there is no channel state information at the transmitter, but channel state information is assumed at the receiver. It is shown that the optimum s...

MIMO Capacity for Spatial Channel Model Scenarios

The capacity of Multiple Input Multiple Output (MIMO) systems has received much attention in recent years. In this paper, we analyse the capacity of MIMO systems for the 3GPP-3GPP2 Spatial Channel Model (SCM). We examine the impact of number of antennas, inter-element distance and mutual coupling, assuming both waterfilling and uniform transmit power allocation schemes, for different SCM scenar...

MIMO capacity results for Rician fading channels

The capacity of a multiple antenna system in Rician fading is considered under the assumption that channel state information (CSI) is available only at the receiver and that the transmitter has knowledge of statistical properties of the fading process though not the instantaneous CSI. Tight upper and lower bounds for the capacity of such a system are derived and a new input signalling scheme th...
