  Abstract

Recently, it is used the radio system with frequency hopping what the channel frequency is changed quickly and aperiodically by the pseudo noise sequence generator system on the transmitter-receiver for precluding a third party predict communications channel frequency. We needed to monitor illegal or unlicensed spectrum use by 3rd party. AMR(Automatic Modulation Recognition) is one method for obtaining modulation type information of blindly intercepted signals. This paper suggests a method of the separation 4 FSK one of the obtained information through AMR. We suggested the method of pile up projection as method of separation 4FSK and verified the usefulness of pile up projection method through the experimental simulation.
