Abstract: A non-data-aided method of calculating an estimate of the sampling frequency offset (SFO) in a digital receiver involves performing a plurality of correlations between two identical sized groups of samples within a received signal where the spacing of the groups is varied for each correlation. In various examples the number of samples in the groups is also varied. For larger symbols, the group of samples may comprise approximately the same number of samples as the guard interval in a symbol and for smaller symbols, the group of samples may comprise approximately the same number of samples as an entire symbol. An estimate of the SFO is determined by identifying the largest correlation result obtained from all the correlations performed. The largest correlation result indicates the largest correlation.
Abstract translation: 用于计算数字接收机中的采样频率偏移（SFO）的估计的非数据辅助方法涉及在接收信号中的两个相同大小的样本组之间执行多个相关性，其中组的间隔对于每个样本 相关性。 在各种实施例中，组中的样品数也是变化的。 对于较大的符号，样本组可以包括与符号中的保护间隔大致相同数量的采样，对于较小的符号，采样组可以包括与整个符号大致相同数量的采样。 通过识别从执行的所有相关性获得的最大相关结果来确定SFO的估计。 最大相关结果表明最大相关。
