Beamformed space time code communication with testing spatial signature generation

Image Number 6 for United States Patent #7889131.

An apparatus, logic and method are provided to improve beamformed space time code (STC) wireless communication. A first device comprising a plurality of antennas receives signals at the plurality of antennas transmitted from a first antenna of a second device. A testing spatial signature for a second antenna of the second device is computed based on the signals received at the plurality of antennas of the first device from the first antenna of the second device. Using the testing spatial signature and the signals received at the plurality of antennas of the first device from the first antenna of the second device, beamforming weights are computed to be applied to a space time code signal to be transmitted from the first device to the second device via the plurality of antennas of the first device.
