Heterogeneous optical and wireless communication networks are pivotal to meet the ever-growing demand of high-throughput data traffic and diverse application scenarios. Versatile methodologies and system interface architectures need to be developed to deliver multiple services in different user environments. Free space optics, millimeter wave, and coherent optical communication enable high-capacity links for wireless users and data center communications, respectively. Moreover, next-generation high-capacity communication systems add more requirements on many aspects including flexibility, hardware or data efficiency, as well as reliability.
In this talk, I will introduce novel key technologies that address these challenges. I will begin by introducing data signal shaping, which optimizes the system throughput flexibly under heterogeneous channel condition and results in better network resource utilization. Next, I will address the system efficiency by performing trade-off analysis, cost-effective system architecture innovation and data-efficient digital signal processing algorithm design. Then I will illustrate efficient multiple-spectra operation and interleaved repetition mapping techniques to enhance the reliability of free space optics and millimeter wave links for outdoor environments. Finally, I will conclude the talk with future research opportunities. Overall, my research outcome contributes to flexible, efficient, and reliable high capacity optical and wireless communication systems.
