ABSTRACT:
According to one embodiment of the invention, a system and a method for maintaining a first history of strength of a first transmission path between a first wireless node and a second wireless node in a multiple input multiple output (MIMO) communication system, maintaining a second history of strength of a second transmission path between a third wireless node and the second wireless node in the MIMO communication system, performing a spatiotemporal correlation between the first history and the second history to determine if any changes in the strength of the first transmission path is observed, and predicting future changes to strength of the second transmission path between the third wireless node and the second wireless node based on the performed special correlation between the first history and the second history.
