Abstract

Polarization-multiplexed LDPC-coded QAM robust to I-Q imbalance and polarization offset is proposed. Efficient mitigation of I-Q imbalance and polarization offset is demonstrated with LDPC-coded turbo equalization by simultaneous MAP detection of symbols transmitted over two orthogonal polarizations. The proposed scheme is much more efficient in I-Q imbalance and polarization offset compensation than conventional approaches.
