摘要：

We propose a novel correlation-based blind polarization demultiplexing technique for coherent optical communication systems. The basic procedure involves the blind estimation of various channel parameters through correlation analysis, and resolving ambiguities using pilot symbols. In a 56 Gb/s/polarizaton multiplexing transmission system employing quadrature phase-shift keying, for both symbol-rate sampling and double symbol-rate sampling, the proposed algorithm achieves the same performance as that of the receiver with known channel parameters and significantly outperforms the constant modulus algorithm.
