Experimental demonstration of digital predistortion for linearization of Mach-Zehnder modulators in direct-detection MB-OFDM ultra-wideband over fiber systems

Digital predistortion for an intensity-modulated direct-detection MB-OFDM UWB system is proposed and experimentally demonstrated to compensate for the non-linear transfer characteristics of the utilized Mach-Zehnder modulator and improve system performance.
