Abstract

A broadband 30-GHz-band radio over fiber (RoF) transmission system has been investigated by using a combination of novel techniques in this thesis. Our efforts focus on star-tree architecture as well as bus architecture connecting remote antenna base stations (BSs) to a central control office (CO) by incorporating OTSSB, SCM, DWDM and frequency-downshifting schemes. These schemes allow the sharing equipment at the CO and therefore enable simple radio distribution architecture to be implemented. In this thesis, we have shown that chromatic dispersion can be almost overcome by implementing a simple method using the dual electrode MZM modulation. An important issue related to maximizing spectral utilization in millimeter-waved-band RoF system has been solved by using wavelength-interleaving DWDM technique incorporating OTSSB modulation. Novel WI-Mux, WI-DeMux and WI-OADM, which are the critical components in wavelength-interleaved DWDM system, have also been studied. Moreover, we have demonstrated a 30-GHz full-duplex RoF network using only a signal light source from CO. In this configuration, BSs are simplified by removing local light sources. In uplink, in addition, a novel technique, frequency-downshifting technique, is used for channel selection and frequency downconversion without electrical frequency downconverter. The principle underlying this novel technique is explained theoretically. (Abstract shortened by UMI.)
