Abstract

This Paper describes a new frequency synchronization technique for OFDM (Orthogonal Frequency Division Multiplexing) demodulators using guard intervals in OFDM. The proposed technique can estimate frequency offset without pilot carriers and reference symbols. The performances of the proposed AFC (Automatic Frequency Control) circuit are studied based on computer simulation. Experimental results are also shown and the AFC circuit operates successfully under the condition of 0dB echo.
