Abstract:
1. A transmitter comprising: a plurality of transmit antennas; circuitry configured to receive channel quality information (CQI), wherein the CQI is received on a per group of orthogonal frequency division multiplexing (OFDM) sub-carrier basis; wherein the circuitry is further configured to generate a channel coded data stream; wherein the circuitry is further configured to perform space frequency block coding (SFBC) encoding on the channel coded data stream in an open loop mode such that the SFBC encoding is performed using a plurality of pairs of OFDM sub-carriers, wherein a portion of the channel coded data stream that is SFBC encoded using a pair of OFDM sub-carriers of an OFDM symbol is SFBC encoded independently of another portion of the channel coded data stream that is SFBC encoded using other pairs of OFDM sub-carriers of the OFDM symbol; and wherein the circuitry is further configured to transmit the SFBC encoded data stream over the plurality of pairs of OFDM sub-carriers using the plurality of transmit antennas as an OFDM signal.
