Simple 2x2 MIMO 60-GHz OFDM RoF System with Single-Electrode MZMs Employing Beating Interference Mitigation and IQ Imbalance Compensation

Abstract

We propose simple 2x2 MIMO 60-GHz RoF systems using single-electrode MZMs. Employing signal-signal beating interference mitigation, IQ imbalance compensation, and bit-loading technique, >40-Gbps OFDM signals over 12-km fiber and 3.5-m wireless transmission are achieved.
