BER and Phase Noise Measurement of Radio over Fiber System based on RF Oscillator Line Width

The first choice link to enter into the global information society is Wireless communication. The progress towards all-around wireless needs budget and easily maintainable radio access points, with simplified signal processing and consolidation of the radio network functions in a central station. Radio over Fiber refers to a system which transmits an optically modulated radio frequency of millimeter range signal from a central station to base stations via an optical fiber link to facilitate wireless access. In this paper, Optical SSB signal is specifically selected as it has tolerance for power degradation due to dispersion effects over a length of fiber. Phase noise and Bit error rate due to various RF oscillator Linewidth is evaluatedby using parameter carrier to noise ratio.
