Automatic Modulation Recognition for Digital Communication Signals
Different modulation techniques are used for different signal transmission. These techniques give versatility to the transmission medium as well as make user easy to work in such computational field. With prior no knowledge of data transmitted and various unspecified parameters at receiver side like the carrier frequency, phase offsets and signal power etc., blind detection of the modulation is challenging. This becomes more difficult at the time of fading. That's why recognizing these modulation schemes is useful for various technical purposes and especially quite significant for the military, wireless and COMINT applications.
