dc.description.abstract본 논문은 convolutional neural network (CNN) 모델에 이미지화 알고리즘을 적용한 자동 변조 분류 기법을 제안한다. 또한 다양한 이미지화 알고리즘을 이용하여 시계열 데이터의 이미지화 작업 후 이를 이용한 CNN 모델의 분류 성능을비교 및 분석한다. 실험 결과, 원시 데이터를 Markov Transition Field (MTF)를 사용하여 이미지화한 후 CNN을 이용한분류를 수행했을 시−6 dB 환경에서는 오차율이 34 %에서 30 %로 감소하였으며, 0 dB 환경에서는 오차율이 37 %에서18 %로 감소하였다. 본 논문은 시계열 데이터의 이미지화가 CNN 기반 변조 분류 성능 개선으로 이어지는 것을 보여줌으로써 이미지화 알고리즘 적용의 유효성을 보여준다.-
dc.description.abstractThis paper presents an automatic modulation classification method that involves the application of various imaging algorithms to a convolutional neural network (CNN). The effect of time-series data imaging on the performance of CNN-based modulation classification is analyzed. Our experiment suggests that converting raw signal data into image data using Markov transition field can reduce the error rate of CNN classification from 34 % to 30 % in case of −6 dB signal to noise ratio (SNR) and from 37 % to 18 % in case of 0 dB SNR. This study shows that time-series imaging is a viable preprocessing method for improving the performance of CNN-based modulation classification.-
