Abstract
In radio over fiber (RoF) links, data speed and the link length is restricted by the number of optical impairment like chromatic dispersion, nonlinearities, phase noise, polarization effect, amplified noises, etc. In the present paper, a technique based on digital signal processing (DSP) has been implemented to mitigate the problem to certain extent, so that the link can find its application for Long-Term Evolution (LTE) and advanced LTE. The accuracy and efficiency of the algorithm has been tested by some standard parameters like error vector magnitude (EVM), symbol error rate (SER), and constellation diagrams. The graphical analysis drawn from simulation software OptiSystem 13.0 reveals the impact of DSP implementation in the optical communication network.
