책소개

무선 통신에서 심층 신경망(DNN)과 심층 강화 학습(DRL)의 적용을 탐색하고 무선 통신 개발을 가속화한다. 본 연구는 한 명의 기본 사용자로 구성된 간단한 인지 무선 시나리오를 제안한다. 보조 사용자 한 명과 함께. 보조 사용자는 주파수 자원을 공유하려고 시도합니다. 기본 사용자 DNN 및 DRL을 기반으로 하는 지능형 전력 알고리즘 모델이 구축된다. MATLAB 플랫폼을 사용하여 모델을 시뮬레이션합니다. 서로 다른 전략에 따른 알고리즘 모델의 성능 분석에서 두 번째 전력 제어 전략이 첫 번째 전력 제어 전략보다 더 보수적인 것으로 나타났다. 두 번째 전력 제어 전략은 첫 번째 전력 제어 전략보다 더 많은 반복을 경험했다. 성공률 측면에서 두 번째 전력 제어 전략은 첫 번째 전력 제어 전략보다 반복 횟수가 더 많습니다. 평균 전송 횟수는 같은 변화 추세를 보이지만 성공률은 1에 이를 수 있다. 기존의 분산 클러스터링 및 전력 제어(DCPC) 알고리듬과 비교했을 때, 이 연구에서 알고리듬의 수렴률이 더 높은 것은 분명하다. DRL에 기반한 제안된 DQN 알고리듬은 수렴을 달성하기 위해 몇 가지 단계만 필요로 하며, 이는 그 효과를 검증한다.
