Abstract
인지 무선 통신 네트워크에서 우수한 성능의 딥러닝 기반 신호 센싱 모델을 구현하기 위해서는 양질의학습데이터가 필요하다. 하지만 실제 환경에서는 변조방식에 따른 서로 다른 양질의 학습데이터를 충분하게확보하지 못하는 경우가 많다. 본 논문에서는 인지 무선 통신에서 적은 학습데이터로 주 사용자의 신호를효과적으로 센싱하기 위해 동적 시간 굽힘을 통한 변조 신호 간 유사성을 이용한 전이학습 기반의 합성곱신경망 모델 구현 방식을 제안한다.
A significant amount of labeled training data is required to implement a superior deep learning-based signal detector for cognitive radio network. In general, however, training data is often not sufficiently guaranteed depending on modulation. In this paper, we propose the deep learning-based modulation signal detection scheme via transfer learning to effectively detect a signal of the primary user with less training data in a cognitive radio network. The proposed scheme also takes into account a convolutional neural network model using the similarity between modulation signals through dynamic time warping.
