This paper presents a GSM-specific assessment of the performance of a radioover fibre link between a remote antenna unit and GSM base station. Theintermodulation distortion (IMD) has been analysed for a system using thesubcarrier multiplexing (SCM). A novel technique using direct sequence spreadspectrum is proposed to minimize the IMD by decreasing the signal amplitudeprior to a direct modulation of a laser diode. The results show that theoptical fibre microcellular is outperforming the full wireless system.
