150-km 103-GHz Direct-Detection OFDM-RoF System Employing Pilot-aided Phase Noise Suppression

Abstract

Pilot-aided phase noise suppression (PPNS) is employed to demonstrate distance-and linewidth-insensitive 103-GHz DD-OFDM-RoF systems. With 10.3-MHz linewidth, PPNS lowers BER of -6-dBm signal from >10(-2) to <10(-3) over 150-km fiber and 2-m wireless transmission.
