32.65-Gbps OFDM RoF signal generation at 60GHz employing an adaptive I/Q imbalance correction

Abstract

We experimentally demonstrated an adaptive I/Q imbalance correction scheme to compensate I/Q-imbalance. With I/Q correction, a 32.65-Gbps OFDM signal at 60 GHz within 7-GHz license-free band is successfully generated and, following 25km SMF transmission, negligible power penalty is observed.
