Abstract
We demonstrate a high reliability mobile fronthaul transmission system using a novel Maximal Ratio Combined receiver (MRC-RX) which combines direct and lite-coherent detections. The maximal ratio combined algorithm employed in the MRC-RX takes the advantage of both direct detection and lite-coherent detection, it ensures the best performance in the case of either low or high optical received power. By using MRC-RX, the error vector magnitude (EVM) performance can be reduced to be smaller than 10% in the proof-of-concept experiment.
