PROJECT DESCRIPTION, MOTIVATION, & RELATED WORK
Multiple-input multiple-output (MIMO) links provide high spectral efficiencies in rich multipath environments through the use of multiple spatial channels in the same system bandwidth [1-3].

 

Closed-loop MIMO architecture [4]

In a network with several transmitting nodes, array antennas at both ends of the MIMO links can be exploited to have multiple links operate in the same channel. Depending on the network topology, each interfering link can transmit fewer modes than it would in an isolated environment, and use the remaining degrees of freedom to avoid or suppress interference. This kind of spatial multiplexing can yield a higher throughput than if the links operated in a time-division multiple-access (TDMA) fashion [5-8].
