이 편지는 샘플 간격이 아닌 채널에 가상 캐리어가 있는 OFDM(직교 주파수 분할 다중화) 시스템을 위한 WDFT(창 이산 푸리에 변환) 기반 채널 추정기에 대한 에지 효과를 다루고 에지 효과를 줄이기 위한 충분한 조건을 도출합니다. 또한, 에지 효과 감소 기법으로 다단계 선형 예측을 갖춘 수정된 WDFT 기반 채널 추정기가 제안됩니다. 시뮬레이션 결과에 따르면 비트 오류율(BER) 5에서 기존 WDFT 기반 채널 추정기에 비해 약 10dB의 신호 대 잡음비(SNR) 이득을 제공하는 것으로 나타났습니다.-3.

Abstract: This letter addresses the edge effect on a windowed discrete Fourier transform (WDFT)-based channel estimator for orthogonal frequency division multiplexing (OFDM) systems with virtual carriers in non-sample spaced channels and derives a sufficient condition to reduce the edge effect. Moreover, a modified WDFT-based channel estimator with multi-step linear prediction as an edge effect reduction technique is proposed. Simulation results show that it offers around 5 dB signal-to-noise ratio (SNR) gain over the conventional WDFT-based channel estimator at bit error rate (BER) of 10-3.
