摘要： In at least some disclosed embodiments, a method includes receiving a burst of data out of multiple bursts of data subject to long-term frequency drift and short-term frequency drift, determining an intercept of the long-term frequency drift based on, at most, the entire burst, and compensating for the long-term drift of a subsequent burst based on the intercept. The method further includes determining a slope of the short-term frequency drift, and compensating for the short-term frequency drift of a subsequent burst based on the slope.
