學位論文簡介

隨著移動互聯網、物聯網、AR/VR、自動駕駛、人工智能等各類新型通信技術的急劇發展,我們將進入一個“萬物互聯”的時代。移動通信技術又將成為萬物互聯的基礎。面對未來爆炸式移動數據流量增長、海量的設備連接、不斷涌現的各類新業務與新應用場景,下一代通信網絡將出現新的變革,無線通信頻譜將朝著更高的頻段如毫米波、可見光等波段搬移以滿足流量與連接數急劇增長的需求。

基于以上背景,本文緊緊圍繞光無線通信系統中的若干關鍵技術展開研究,重點研究了光無線系統中的高頻譜效率的調制格式、功率域非正交多址接入技術(NOMA)、實時硬件算法實現以及低成本光無線系統中的性能增強方案,旨在進一步提升光無線接入系統的頻譜效率與傳輸容量、提高用戶連接數目、實現更大靈活性、改善性能的同時降低算法復雜度、滿足硬件可實現性。
