Abstract
A method is provided for estimating at least one offset of a communication in a multicarrier communication system. The method comprises receiving a plurality of subcarriers wherein the plurality of subcarriers contain the subcarrier that is subject to the distortion; and generating a plurality of first channel estimates for a respective plurality of received subcarriers that are not subject to the distortion. The method further comprises processing a number of the plurality of first channel estimates for the respective plurality of received subcarriers that are not subject to the distortion to generate a second channel estimate for the subcarrier that is subject to the distortion; and estimating an offset associated with the subcarrier that is subject to the distortion.
Claims2
A computer implemented method for estimating at least one offset of a communication in a multicarrier communication system, the method comprising:
- receiving a plurality of subcarriers wherein at least one of the plurality of subcarriers contain a subcarrier that is subject to the distortion;
- generating a plurality of first channel estimates for a plurality of received subcarriers that are not subject to the distortion;
- processing a number of the plurality of first channel estimates for the plurality of received subcarriers that are not subject to the distortion to generate a second channel estimate for the subcarrier that is subject to the distortion;
- and
- estimating an offset associated with the subcarrier that is subject to the distortion by:
- receiving a known reference signal transmitted for the subcarrier that is subject to the distortion,
- multiplying the second channel estimate with the known reference signal to produce a first value, and
- subtracting the first value from the received known reference signal to produce the estimated offset.
