COMPENSATION FOR NOISE IN OPTICAL-ELECTRONIC DEVICES WITH THE USE OF WIENER—HOPF FILTER



Abstract. The problem is considered of noise compensation on the base of Wiener—Hopf linear filtering with the use of sampling of signal values and its derivatives in initial and terminal points of interpolation interval. Effectiveness of the method is calculated for a specified noise correlation function. Possibility of noise compensation is confirmed by experiments carried out with a model of laser optical-electronic system. Experimental oscillograms are presented.
Keywords: signal, noise compensation, sampling, effectiveness, photodetector, experimental setup, correlation function.
