Frequency offset correction in multicarrier receivers |
摘要 |
<p>There is provided an apparatus and method for compensating for a frequency offset in an orthogonal frequency division multiple)ing (OFDM system. In the frequency offset compensating apparatus, a correlating portion demodulates input data by fast Fourier transformation, delays a demodulated symbol by a predetermined period, and correlates a symbol demodulated during the delay to the delayed symbol. A pilot position detecting portion compares the correlation with a predetermined pilot position and e)tracts a correlation corresponding to the pilot position. A frequency offset compensating portion estimates a frequency offset to the e)tracted correlation if the e)tracted correlation is a predetermined ma)imum and shifts the phase of pilot data by the estimated frequency offset. <IMAGE></p> |
