PARALLEL AUTOMATIC FREQUENCY OFFSET ESTIMATION APPARATUS AND A METHOD THEREOF, PARTICULARLY FOR PRECISELY ESTIMATING AND COMPENSATING A FREQUENCY OFFSET IN AN INITIAL STAGE

摘要

PURPOSE: A parallel automatic frequency offset estimation apparatus and a method thereof are provided to calculate a frequency and a phase difference regarding a distorted signal in parallel in a certain interval of a preamble.;CONSTITUTION: A reception unit(200) receives a data frame, and a frequency offset estimating unit(300) calculates frequency phase deviations corresponding to each interval at different bit interval in parallel in a certain section of a received data frame and sums up the frequency phase deviations. The frequency offset estimator adds the sum result to a frequency phase deviation and outputs the added result.;COPYRIGHT KIPO 2010
