OFDM FREQUENCY OFFSET ESTIMATION APPARATUS AND METHOD |
摘要 |
A frequency offset estimator (400) and corresponding method (600) provides a frequency offset estimate (415) for an OFDM signal. The estimator comprises a data parser (403) coupled to an input signal (401) and arranged to select a group of symbols (305 - 311) or corresponding samples corresponding to predetermined symbols from the input signal and a processor (405) arranged to provide a correlation corresponding to the symbols, where the correlation corresponds to a frequency offset estimation for the input signal and is determined in a sequential fashion so that the correlation is provided concurrently with the last symbol or sample of the group of symbols to be selected. |
