摘要

提出了一种抗I-Q不平衡和极化偏置的极化复用ldpc编码QAM。ldpc编码turbo均衡通过同时MAP检测在两个正交极化上传输的符号，有效地缓解了I-Q不平衡和极化偏移。该方案在I-Q不平衡和极化补偿方面比传统方法更有效。

Polarization-multiplexed LDPC-coded QAM robust to I-Q imbalance and polarization offset

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.
