Claim Text:
1. A method comprising: selecting a plurality of carrier tracking subcarriers from a plurality of subcarriers of an orthogonal frequency division multiplexing (OFDM) signal partially based on a predetermined number indicating a number of subcarriers between adjacent carrier tracking subcarriers of the plurality of carrier tracking subcarriers; and communicating at least a portion of a frame of data using the OFDM signal having first numbers of bits per symbol of the frame of data modulating the plurality of carrier tracking subcarriers of the OFDM signal and second numbers of bits per symbol of the frame of data modulating the other subcarriers of the plurality of subcarriers, wherein the first numbers of bits per symbol are based on corresponding performance estimates for the carrier tracking subcarriers and numbers of bits that provide a first target performance margin, and wherein the second numbers of bits per symbol are based on corresponding performance estimates for the other subcarriers and corresponding numbers of bits that provide a second target performance margin.
