The apparatus uses a receiver for each pair of frequencies at which the information is transmitted, a synchronizer for synchronizing the transmitter and receives, a correlator and a code sequence generator. The receiver is alternately operated at one of two frequencies over a predetermined period, and each correlator is provided with a number of sections equal to the maximum number of codes to be transmitted at each of the frequencies.
