摘要：
A system including an estimation module, a processing module, and a control module. The estimation module is configured to generate a first set of channel estimates for a plurality of subcarriers of a received signal. The processing module is configured to generate a second set of channel estimates for the plurality of subcarriers, in which the second set of channel estimates are generated based on the first set of channel estimates. The control module is configured to estimate a preamble sequence in the received signal based on each of (i) the first set of channel estimates and (ii) the second set of channel estimates.
