A 2x2 multiple-input multiple-output (MIMO) architecture using dual-polarized antennas (DPAs) is considered with orthogonal frequency division multiplexing (OFDM). The performance of DPAs is evaluated for adaptive polarization (AP) transmissi

This setup illustrates the principle of coherent detection and digital signal processing (DSP) for a coherent 112Gb/s QPSK signal. The system performance is limited by noise (added in front of the receiver), chromatic dispersion and PMD (taking place
