Patent ID: 7345989

Claim:
A wireless apparatus comprising: an adaptive channelization controller to determine which of a plurality of predetermined sub-channels to use to support a multicarrier wireless link, based on channel state information; and a receiver chain to process a received multicarrier signal associated with said multicarrier wireless link based on control information output by said adaptive channelization controller; wherein said receiver chain includes: a frequency demultiplexer to separate said received multicarrier signal into multiple signal portions based on frequency, said multiple signal portions corresponding to said plurality of predetermined sub-channels; and a plurality of Fourier transform units to separately process said multiple signal portions output by said frequency demultiplexer, said plurality of Fourier transform units including at least a first Fourier transform unit to process a first signal portion and a second Fourier transform unit to process a second signal portion; and an adaptive parallel to serial converter to receive output streams from said plurality of Fourier transform units and to merge said output streams into a serial stream based on control information from said adaptive channelization controller.
