A method for generating an orthogonal frequency division multiplexing (OFDM) frame for wireless communications begins by generating a preamble of the OFDM frame, wherein the preamble includes training information and signal information. The method continues by generating a plurality of data fields of the OFDM frame, wherein each of the plurality of data fields includes a plurality of subcarriers, wherein at least some of the plurality of data fields includes, at most, three of the plurality of subcarriers allocated for a pilot signal.
