Abstract
A channel estimator is configured for determining a gain adjustment for a received wireless signal having a prescribed plurality of tones. The channel estimator is configured for generating, for each of the tones, a corresponding pseudo power value representing a detected power level for the corresponding tone. An accumulated pseudo power value is obtained based on accumulating the respective pseudo power values of the prescribed plurality of tones. Each of the pseudo power values is selectively adjusted by an adjustment factor based on a determined difference between the accumulated pseudo power value relative to an expected accumulated power level relative to a prescribed dynamic range. The pseudo power values are then output for decoding of data modulated at the respective tones.
