Dispersion compensating radio over fiber (RoF)‎ for 5G radio access network

Abstract EN

The new developments and generations of mobile systems needs new radio access networks, this is because of higher frequency spectrum and lower coverage of base stations and then higher number of base stations, causes higher impairments and the signal quality will be decreased, this is because of the increase of interference.

In this paper a new proposed radio access network has been presented for the Fifth Generation (5 G) mobile system with the use of radio over fiber (RoF) system instead of microwave link and a mesh topology.

Because of the dispersion effect in optical fibers, data rate transmission will be decreased, in this paper using radio over fiber means minimization of this problem has been studied.

Moreover, a new technique to compensate the dispersion effect presented, the results shows that the proposed work will decrease the effect of dispersion and then higher data rate and better signal quality between the base stations in the mobile system as shown in the results
