채널 상황에 따라 ICI 감소 모드를 선택할 수 있는 적응형 사전 FFT 등화기와 순환 싱크 함수 행렬을 사용하는 DIME(Degenerated-Inverse-Matrix-based Channel Estimator)을 사용하여 OFDM 전송을 위한 매력적인 접근 방식을 제시합니다. 전송된 부반송파에 의해 고유하게 결정됩니다. 시뮬레이션 결과 외에도 적응형 사전 FFT 이퀄라이저와 DIME을 갖춘 제안 시스템은 SDR(Software Defined Radio) 기반 테스트 베드를 사용하여 실험실 테스트를 거쳤습니다. 시뮬레이션과 실험 결과를 통해 100Mbps 이상의 속도에서 시스템이 10Mbps 미만의 비트 오류율을 제공할 수 있음을 입증했습니다.-3 200GHz 대역에서 1.9μs의 지연 확산(최대 지연 경로 7.3μs)으로 이동 속도가 5km/h 이상인 고속 다중 경로 페이딩 채널의 경우.

Abstract: We present an attractive approach for OFDM transmission using an adaptive pre-FFT equalizer, which can select ICI reduction mode according to channel condition, and a degenerated-inverse-matrix-based channel estimator (DIME), which uses a cyclic sinc-function matrix uniquely determined by transmitted subcarriers. In addition to simulation results, the proposed system with an adaptive pre-FFT equalizer and DIME has been laboratory tested by using a software defined radio (SDR)-based test bed. The simulation and experimental results demonstrated that the system at a rate of more than 100 Mbps can provide a bit error rate of less than 10-3 for a fast multi-path fading channel that has a moving velocity of more than 200 km/h with a delay spread of 1.9 µs (a maximum delay path of 7.3 µs) in the 5-GHz band.
