M차 거듭제곱을 이용한 OFDM 신호 시간 오프셋 보상 알고리즘

초록

In order to demodulate an unknown signal in a non-cooperative context, timing offset, phase offset, and frequencyoffset of the received signal must be compensated. For Orthogonal Frequency Division Multiplexing (OFDM) signals,it is important to compensate timing offset to remove the cyclic prefix. In this paper, we propose an algorithmutilizing the M-th power of the received signals for timing offset compensation in OFDM systems and analyze itsperformance through computer simulations.
