dc.description.abstract보호구간이 없는 Orthogonal Frequency Division Multiplexing (OFDM) 시스템을 사용하면 보호구간이 있는 OFDM 시스템보다 대역폭 효율을 향상시킬 수 있다. 보호구간이 없는 OFDM 시스템에서 Inter-Symbol Interference (ISI)와 Inter-Carrier Interference (ICI)를 제거하는 새로운 기법을 제안한다. 제안된 알고리즘은 Pseudo-Decorrelator에 기초하는 보호구간이 없는 OFDM 시스템의 복조 기법이며, PD 알고리즘이라고 부르기로 하자. 모의실험 결과는 PD 알고리즘이 보호구간이 없는 OFDM 시스템에서 ISI와 ICI를 효과적으로 제거할 수 있음을 보여준다. PD 알고리즘은 기존의 보호구간이 없는 OFDM 시스템보다 월등히 좋은 BER 성능을 나타낸다. Orthogonal frequency division multiplexing (OFDM) systems without guard interval can enhance the bandwidth performance more efficiently than the systems with guard interval. In this paper, a new technique for an OFDM system without guard interval, which can eliminate inter-symbol interference (ISI) and inter-channel interference (ICI), is presented. The proposed algorithm is a new demodulation technique, based on the Pseudo-Decorrelator, and it is named PD algorithm. Simulation results show that the PD algorithm can combat ISI and ICI efficiently for an OFDM system without guard interval. Thus, the BER performance of the PD algorithm is much better than that of an traditional OFDM system without guard interval.en_US
