Patent ID: 8320487

Claim:
A method for processing signals in a communication system, the method comprising: in a receiver: determining to transmit channel estimation data at a first frequency based upon a Doppler shift frequency being less than or equal to a first threshold value; determining to transmit the channel estimation data at a second frequency based upon the Doppler shift frequency being greater than the first threshold value and less than or equal to a second threshold value; and determining to not transmit the channel estimation data based upon the Doppler shift frequency being greater than the second threshold value; in a transmitter: generating outgoing signals wherein: outgoing beamformed signals are generated based on one of the first and the second frequency of the channel estimation data; alternatively, based on the channel estimation data not being transmitted, outgoing signals are generated using one of space time block coding or space frequency block coding techniques; and concurrently transmitting the outgoing signals via a communication medium utilizing a selected one of the beamforming or coding techniques.
