Abstract:
1. A wireless communication device comprising: a variable bandwidth receiver configurable receive OFDM symbols over different bandwidths using multiple antennas; a transmitter configured to transmit a reference signal; and antenna selection circuitry to select some of the antennas, wherein the receiver is arranged to receive OFDM symbols over a wideband channel using the selected antennas by processing two or more sets of subcarriers and arranged to receive OFDM symbols over a subchannel by processing a single set of subcarriers using the selected antennas, wherein the transmitter is arranged to transmit data using the selected antennas, wherein two or more of the antennas are selected based on channel conditions determined from the transmitted reference signal, the selected antennas being a subset of the multiple antennas and include less than all of the antennas, and wherein each set of subcarriers comprise a predetermined number of subcarriers.
