dc.description.abstract보호구간이 없는 Orthogonal Frequency Division Multiplexing-Code Division Multiplexing Access(OFDMCDMA) 시스템을 사용하면 보호구간이 있는 OFDM-CDMA 시스템보다 대역폭 효율을 향상시킬 수 있다. 보호구간이 없는 OFDM-CDMA 시스템에서 Inter-Symbol Interference(ISI)와 Inter-Carrier Interference(ICI)를 제거하는 새로운 기법을 제안한다. 제안된 알고리즘은 Pseudo-Decorrelator에 기초하는 보호구간이 없는 OFDM-CDMA 시스템의 복조 기법이며, PD 알고리즘이라고 부르기로 하자. 모의실험 결과는 PD 알고리즘이 보호구간이 없는 OFDM-CDMA 시스템에서 ISI와 ICI를 효과적으로 제거할 수 있음을 보여준다. PD 알고리즘은 기존의 보호구간이 없는 OFDM-CDMA 시스템보다 좋은 BER 성능을 나타낸다. Orthogonal frequency division multiplexing-code division multiplexing access(OFDM-CDMA) 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-CDMA 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-CDMA system without guard interval. The BER performance of the PD algorithm is much better than that of a conventional OFDM-CDMA system without guard interval.en_US
