Patent ID: 8433002

Claim:
A method comprising: extracting pilot and data subcarriers from a frame control header (FCH) of a signal received via a wireless channel; determining an initial channel estimate (CE) based on the extracted FCH pilot subcarriers by dividing the extracted FCH pilot subcarriers of the received signal by known FCH pilot subcarriers and a normal boosting factor corresponding to the FCH pilot subcarriers, wherein the initial CE is approximately equal to a frequency response of the wireless channel multiplied with a zone boosting factor of a PUSC (partial usage of subchannels) zone; generating an interpolated CE based on the initial CE by estimating frequency responses of the channel for the extracted FCH data subcarriers; from the interpolated CE, extracting a channel estimate corresponding to the FCH data subcarriers; dividing the extracted FCH data subcarriers by the extracted channel estimate to form equalized FCH data subcarriers; and determining the FCH based on the equalized FCH data subcarriers.
