Abstract

In this paper we implement a first multi-gigabit real-time dual-polarization CO-OFDM receiver in a 2$\,\times\,$2 multiple-input multiple-output (MIMO) configuration. The experimental setup consists of four 1.5 Giga samples per second (GS/s) high-speed analog-to-digital converters (ADC) and one Stratix III field-programmable gate array (FPGA). The signal streams are processed in real-time mode, and the data rates of 3.33 Gb/s and 6.67Gb/s are realized for 4-QAM and 16-QAM, respectively.
