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 can be determined. Simulation results show that the proposed filter is capable of minimizing the effects of phase and shot noise, that are superimposed on the DPSK signal, regardless the transmitted sequence.
