学位论文简介

随着移动互联网、物联网、AR/VR、自动驾驶、人工智能等各类新型通信技术的急剧发展,我们将进入一个“万物互联”的时代。移动通信技术又将成为万物互联的基础。面对未来爆炸式移动数据流量增长、海量的设备连接、不断涌现的各类新业务与新应用场景,下一代通信网络将出现新的变革,无线通信频谱将朝着更高的频段如毫米波、可见光等波段搬移以满足流量与连接数急剧增长的需求。

基于以上背景,本文紧紧围绕光无线通信系统中的若干关键技术展开研究,重点研究了光无线系统中的高频谱效率的调制格式、功率域非正交多址接入技术(NOMA)、实时硬件算法实现以及低成本光无线系统中的性能增强方案,旨在进一步提升光无线接入系统的频谱效率与传输容量、提高用户连接数目、实现更大灵活性、改善性能的同时降低算法复杂度、满足硬件可实现性。
