Radio-over-Fibre Technology for Broadband Wireless Communication Systems -The research in this thesis focussed on the feasibility of using both single-mode and

multimode fibres to distribute high-frequency microwave signals to simplified remote

radio antenna units.　An alternative radio-over-fibre technique, termed Optical

Frequency Multiplication (OFM) has been investigated.　OFM entails the periodic

filtering of a swept optical　signal at the headend followed by photodetection at the

radio access unit.　A low sweep frequency (e.g. 3 GHz) is used.　After photodetection

at the remote radio access unit, high-frequency (>21 GHz) harmonic components of

the sweep signal are generated.　The desired microwave signal is selected by means of

bandpass filtering, amplified, and radiated　by the antenna.　Modulated microwave

carriers are generated by intensity modulating the frequency-swept optical signal.
