Abstract :
Blind electronic polarization demultiplexing in coherent optical receivers using the constant modulus algorithm occasionally suffers from singularities. The introduction of constraints in the polarization demultiplexer´s transfer function compensates for this deficiency, greatly enhancing convergence speed.
