学位论文简介

本论文的研究内容主要分三个方面，其一是面向光纤接入PON的直接检测光纤系统方面的研究，其二是面向室内光无线接入的可见光通信方面的研究，其三是面向未来光纤无线混合网络的RoF通信方面的研究。在面向光纤接入PON的直接检测光纤系统方面，我们提出了若干DSP方案，搭建了相关实时实验系统，同时提出了若干有利于提高直接检测光纤系统速率的新型传输方案。在面向室内光无线接入的可见光通信方面，我们研究了若干有利于解决可见光通信系统中常见敏感问题的DSP方案，同时展示了若干超Gbps传输速率的实时可见光通信系统。在面向未来光纤无线混合网络的RoF通信方面，我们首先围绕Q波段研究了一个相关的实时RoF通信系统，其次主要围绕W波段RoF通信系统及其相关DSP技术展开了工作。
