METHOD FOR ESTIMATING FREQUENCY OFFSET IN ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING SYSTEM |
摘要 |
Provided is a method for estimating a frequency offset. The method for estimating the frequency offset may include calculating autocorrelation values associated with a Cyclic Prefix (CP) for a reception signal, dividing the calculated autocorrelation values into first autocorrelation values associated with an interval where a signal exists and second autocorrelation values associated with an interval where a signal does not exist, determining whether to use the divided second autocorrelation values; and estimating the frequency offset using the second autocorrelation values determined to be used and the first autocorrelation values.
