RADIO OVER FIBER LINK WITH ADAPTIVE ORDER n-QAM OPTICAL PHASE MODULATED OFDM AND DIGITAL COHERENT DETECTION

摘要

Successful digital coherent demodulation of asynchronous optical phase-modulated adaptive order QAM (4, 16, and 64) orthogonal frequency division multiplexing signals is achieved by a single reconfigurable digital receiver after 78 km of optical deployed fiber transmission.
