1. A method of transmitting a wideband pilot in a wireless multi-carrier communication system, comprising:

  • processing at least one pilot symbol with a pseudo-random number (PN) code to obtain a sequence of pilot chips for the wideband pilot;

    processing data symbols in accordance with a multi-carrier modulation scheme to obtain a sequence of data chips;

    time division multiplexing the sequence of pilot chips with the sequence of data chips to obtain a time division multiplexed (TDM) sequence of pilot and data chips, wherein a plurality of periods for the sequences of data chips are provided between periods for the sequences of pilot chips; and

    transmitting the TDM sequence of pilot and data chips.
