Method for generating and transmitting pilot sequence using non-cazac sequence in wireless communication system

Disclosed is a method for a transmitter to transmit a pilot sequence to a receiver in a wireless communication system, the method comprising: generating a baseline sequence having non-constant amplitude zero auto correlation (non-CAZAC) properties; generating a plurality of pilot sequences by shifting the baseline sequence on the time axis; and transmitting, to a receiver, any one pilot sequence selected from among a sequence set comprising the plurality of pilot sequences.
