Digital Predistortion Algorithm of Advance Coherent Modulation Schemes Enabling Radio over Fiber for Access Networks
Digital predistortion algorithms are demonstrated for 5G back-bone optical systems employing 64-QAM and 256-QAM advance modulation formats. The performance of the digitally linearized systems is compared experimentally and using simulation with standard coherent transmission systems.
