Patent ID: 7177297

Claim:
A method of receiving a wideband pilot in a wireless multi-carrier communication system, comprising: obtaining a sequence of received chips that includes a time division multiplexed (TDM) sequence of received pilot and data chips; demultiplexing the sequence of received chips to obtain a sequence of received pilot chips for the wideband pilot and a sequence of received data chips; processing the sequence of received pilot chips with a pseudo-random number (PN) code to obtain a sequence of chip-spaced gain values based upon a plurality of channel gain estimates for a plurality of propagation paths for the wideband pilot and to obtain the plurality of channel response estimates for the plurality of subbands based upon transformations of the sequence of chip-spaced gain values; and processing the sequence of received data chips in accordance with a multi-carrier demodulation scheme and with the plurality of channel response estimates to obtain recovered data symbols.
