Polarization Crosstalk Reduction by Successive Interference Cancellation for Polarization-Tracking-Free PDM Radio over Fiber Mobile Fronthaul System

Abstract

We propose a novel polarization-tracking-free PDM fiber-wireless mobile fronthaul system by using SIC to reduce the crosstalk caused by imperfect PDM demultiplexing. Our experimental results show this proposed PDM demultiplexing scheme greatly relieves spectral limitation.
