Abstract
A method of transmitting pilots id disclosed. The method of transmitting pilots includes transmitting pilots over N orthogonal frequency division multiplexing (OFDM) symbols, wherein a pilot at subcarrier k for OFDM symbol n is determined to have time varying characteristic, thereby to prevent the cause of spectral lines.
