In thiS paper we propose a. linear time invariant filter for optical heterodyne DPSK receiver to combat laser phase noise.Using optimal control techniques, we convert the filtering problem into an equivalent identification problem in which the filter parameters are the unknowns.Using variations arguments, we derive the necessary conditions of optimality on the basis of which the filter parameters ...
