Patent ID: 7953039

Claim:
For use in a subscriber station capable of communicating with a base station of an orthogonal frequency division multiplexing (OFDM) network, a method of controlling downlink transmissions to the subscriber station comprising the steps of: receiving a first pilot signal from a first antenna of the base station; receiving a second pilot signal from a second antenna of the base station; estimating the channel between the base station and subscriber station based on the received first and second pilot signals; determining a set of OFDM symbol processing parameters based on the step of estimating the channel, wherein the OFDM symbol processing parameters are usable by the base station to control the relative gains and the relative delays of OFDM symbols transmitted from the first and second antennas; transmitting the OFDM symbol processing parameter set to the base station; receiving first processed OFDM symbols transmitted from the first antenna; and receiving second processed OFDM symbols transmitted from the second antenna.
