Abstract
A system and method for vector wireless radio communication (multiple modes or signal streams) between a first communication device and a second communication device using radio frequency (RF) communication techniques. At each communication device, signals are received at a plurality of antennas representing a plurality of modes simultaneously transmitted by the other communication device, wherein each mode is a signal stream. A transmit matrix is computed from signals received at the plurality of antennas. The transmit matrix distributes a plurality of modes among a plurality of antenna paths each associated with a corresponding one of the plurality of antennas of the first communication device, and is applied to the plurality of modes to be simultaneously transmitted from the plurality of antennas of one communication device to the other communication device.
