Homodyne OFDM using Simple Optical Carrier Recovery [PDF]
Optical Fiber Communication Conference, 2014 We demonstrate a novel optical injection locking approach to carrier recovery in RF-pilot aided OFDM. Any need for optical pre-filtering is eliminated and only very narrow guard bands are required.
