Abstract
A high rate radio frequency (RF) link system and method for spatially multiplexing data transmission is presented. The system can comprise a common communications point characterized by a first collection of antennas having independent channels interconnected with a known latency connection to a central process location, such as with optical fiber; and a second similarly configured collective endpoint or set of endpoints wherein multi-path between the first collection and the second collection is negligible. Signal decorrelation between independent channels is achieved through a combination of spatial separation and signal processing. In one aspect, decorrelation is performed using near-maximum likelihood Multiple-Input Multiple-Output signal processing.
