유연한 무선 네트워크를 가능하게 하는 WDN(Wireless Distributed Network)의 기능 중 하나로, 우수한 무선 자원 관리를 위해 OFDM 시스템에 동적 스펙트럼 액세스(Dynamic Spectrum Access)가 적용되는 것으로 추정됩니다. 본 연구에서는 이러한 WDN의 기본 기술로서 순환정지 특성을 기반으로 한 OFDM 신호 검출을 다룬다. 이전의 관련 연구는 주로 몬테카를로 방법을 기반으로 한 소프트웨어 시뮬레이션에 의존했습니다. 이 논문은 검출기의 설계 매개변수와 검출 성능 사이의 관계를 분석적으로 명확하게 설명합니다. 감지 성능은 수신 필터의 전달 함수를 포함한 여러 설계 매개변수를 사용하여 공식화됩니다. RF부와 FPGA로 구성된 검출기를 이용하여 무선주파수(RF) 신호에 대한 하드웨어 실험도 진행한다. 이를 통해 분석식에 의해 계산된 오경보 확률과 비검출 확률로 나타나는 검출 특성이 하드웨어 실험에서 구한 특성과 잘 일치함을 검증하였다. 우리의 분석 및 실험 결과는 요구되는 성능 기준을 만족시키기 위한 신호 검출기의 매개변수 설계에 유용합니다.

Abstract: As one functionality of the wireless distributed network (WDN) enabling flexible wireless networks, it is supposed that a dynamic spectrum access is applied to OFDM systems for superior radio resource management. As a basic technology for such WDN, our study deals with the OFDM signal detection based on its cyclostationary feature. Previous relevant studies mainly relied on software simulations based on the Monte Carlo method. This paper analytically clarifies the relationship between the design parameters of the detector and its detection performance. The detection performance is formulated by using multiple design parameters including the transfer function of the receive filter. A hardware experiment with radio frequency (RF) signals is also carried out by using the detector consisting of an RF unit and FPGA. Thereby, it is verified that the detection characteristics represented by the false-alarm and non-detection probabilities calculated by the analytical formula agree well with those obtained by the hardware experiment. Our analysis and experiment results are useful for the parameter design of the signal detector to satisfy required performance criteria.
