METHOD FOR ESTIMATING LOW COMPLICATED OFDM INTEGER FREQUENCY OFFSET, OFDM INTEGER FREQUENCY OFFSET ESTIMATOR USING SAME AND SYSTEM OF OFDM RECEIVER

摘要

The present invention relates to an orthogonal frequency division multiplexing (OFDM) demodulation technology and, more specifically, an OFDM integer frequency offset estimation technology. The OFDM signal with high frequency efficiency is widely used as physical layer standard technology for the standards of Wi-Fi and Long term evolution (LTE). The OFDM integer frequency offset estimation method of the present invention comprises a step of generating n number of binding sub carrier by transferring and overlapping frequency of g number of received sub carriers among n number of received sub carriers consisting of a received OFDM symbol.;COPYRIGHT KIPO 2015
