Claim 1

A TRANSMITTER-RECEIVER STATION IN A COMMUNICATION SYSTEM COMPRISING; AN M-NUMBER OF LOCAL GENERATORS FOR SIMULTANEOUSLY SEPARATELY GENERATING BROAD-BAND GAUSSIAN NOISE VOLTAGES, X1, X2, ... XM, RESPECTIVELY; A TRANSMITTER FOR TRANSMITTING SIGNAL XO COMPOSED OF THE SUM OF SAID NOISE VOLTAGE; A RECEIVER FOR RECEIVING, AFTER A TRANSMSSION TIME DELAY T, SAID SIGNAL XO MODIFIED BY ADDITIVE NOISE VOLTAGES N OF THE TRANSMISSION MEDIA; MEANS FOR RELATIVELY DELAYING THE LOCALLY GENERATED VOLTAGES X1, X2, ... XM, WITH RESPECT TO THE RCEIVED SIGNAL XO0N; A PLURALITY OF MULTIPLIERS, EACH MULTIPLIER HAVING TWO INPUTS, ONE INPUT OF EACH MULTIPLIER BEING CONNECTED TO THE OUTPUT OF SAID RECEIVER AND THE OTHER INPUT OF EACH MULTIPLIER BEING CONNECTED, RESPECTIVELY, TO THE OUTPUT OF ONE OF SAID LOCAL GENERATORS FOR MULTIPLYING THE RECEIVED XO+N SIGNAL WITH EACH OF SAID SEPARATE VOLTAGES X1 TO XM, RESPECTIVELY;
