- 초록
- Generally in OFDM system, we intentionally set the FFT start point offset for the purpose of preventing from ICI in the perspective of implementation, but it will bring phase rotation that can not be compensated by simple LS channel estimation. Therefore, in this paper, we showed that uncoded BER performances were enhanced by the phase compensation method when we used the FFT start point offset in the presence of received time synchronization errors. © 2013 IEEE.
