Abstract:
1. A method, comprising: receiving a block of symbols; determining a first group of samples, the first group of samples corresponding to a first group of symbols included in the block of symbols, the first group of samples corresponding to a first interval determined in accordance with a maximum frequency offset; determining, in accordance with the first group of samples, a first frequency offset estimation associated with the block of symbols; back-rotating one or more symbols in the block of symbols in accordance with at least the first frequency offset estimation; producing a second group of samples, the second group of samples corresponding to a second group of symbols that are based at least in part on symbols that are back-rotated according to the first frequency offset estimation, wherein the second group of samples correspond to a second interval that is longer than the first interval determined in accordance with the maximum frequency offset; and determining, in accordance with the second group of samples, a second frequency offset estimation associated with the block of symbols.
