Abstract

In this paper, we demonstrate multiband orthogonal frequency division multiplexing (MB-OFDM) transmission of quadrature phase shift keying (QPSK) modulation with 200-Mb/s bit rate by all-optical frequency up-conversion using external modulator for ultrawideband (UWB) applications to 60-GHz band radio-over-fiber (RoF) network. Error vector magnitude (EVM) measurements are used to evaluate the performance of our system and an EVM root mean square (rms) of 12.6% at 60 GHz is obtained with our technique and corresponds to bit error rate (BER) below $10^{-9}$, in compliance with standard requirements.
