Abstract:

With the proliferation of Internet-connected devices and the emerging all types of wireless services requiring high bandwidth, low latency and reliability, the next-generation 5G wireless communication system is actively researched and standardized. The overwhelming exploration of the wireless traffic largely relies on advanced optical backbone networks, which provides high bandwidth and low loss connections from the core network to all types of cells. A fiber-wireless integrated system would significantly improve the mobile data network in performance, capacity and cost reduction. This Ph.D. dissertation focuses on system design and digital signal processing (DSP) techniques for the fiber-wireless integrated system and the fiber-wireless integrated channel, to provide higher capacity, improved reliability and reduced latency for next-generation wireless systems. Specifically, the design and optimization are in three aspects: (a) improving the mobile fronthaul (MFH) transmission quality within the physical limitations of the fiber link, for both analog and digital MFH solutions to reduce the signal PAPR and improve the performance with joint digitization/channel coding; (b) designing the advanced waveforms (GFDM, OCDM, NOMA) adapting to the high-frequency millimeter-wave (MMW) fiber-wireless integrated system, to enhance the existing modulation and multiple access technologies in different application scenarios; (c) jointly combining all available electromagnetic (EM) frequency resources in the network as the all-spectrum wireless access system.
