Summary:
In this master thesis, the radio-over-fiber (RoF) technology, which enables the
integration of wireless and optical systems, is presented. This thesis focuses
on radio-frequency (RF) signal generation and transmission techniques over
optical fiber in RoF systems, particularly on the uplink connection for mm-wave
signals. Initially, the reasons for using mm-wave RoF technology, its main
features, its advantages and limitations, as well as its application areas are
stated. A comparative overview of modulation formats for wireless and optical
signals in those hybrid systems follows. The impairments that signals undergo
along transmission are also referred. Subsequently, a brief overview of the
basic RF signal generation and transmission techniques in RoF networks, as well
as a short description of some important papers in this field is given.
Finally, the importance of coexistence of RoF technology with other optical
access technologies, such as WDM, is emphasized, in order to exploit the
existing infrastructure, but also to simultaneously provide wireless and wired
services in heterogeneous access networks, with the simultaneous full-duplex
transmission of multiple signal bands. The usage of mm-wave RoF systems
provides cost-efficiency and low complexity, transparency in the network nodes,
dynamic resources allocation and simultaneously high-performance transmission.
Therefore, they are considered as promising solution for future broadband
multi-service access networks.
