免授權(quán)頻譜共享原理與技術(shù) 內(nèi)容簡介
在萬物互聯(lián)時代，頻譜資源會越來越緊張。將蜂窩通信擴展到免授權(quán)頻段是緩解當前頻譜資源短缺問題的一個重要手段。本書系統(tǒng)地闡述免授權(quán)頻譜共享原理與技術(shù)，共7 章。第1 章為緒論，介紹免授權(quán)頻譜共享的提出及免授權(quán)頻譜共享方案等。第2 章介紹免授權(quán)頻譜共享方案LTE-LAA 在理想情況、捕獲效應及不完美頻譜探測下的性能。第3 章介紹LTE-LAA 方案的智能優(yōu)化，分別介紹基于混沌Q 學習的CWS 選擇算法及基于Q 學習的能量閾值優(yōu)化算法。第4 章介紹D2D 通信下的免授權(quán)頻譜共享方法，分別介紹基于多智能體深度強化學習的D2D通信資源聯(lián)合分配算法和基于DDQN 的D2D 直接接入免授權(quán)頻譜算法。第5 章介紹基于無人機平臺的免授權(quán)頻譜共享方法，分別介紹基于混合頻譜共享的軌跡優(yōu)化和資源分配算法，以及基于全頻譜共享的軌跡和功率優(yōu)化算法。第6 章介紹基于AI 的免授權(quán)頻譜共享方法，分別介紹人工智能技術(shù)、基于深度Q 學習的免授權(quán)頻譜接入算法及基于平均場近似的免授權(quán)頻譜接入算法。第7 章是總結(jié)與展望。
