Various embodiments associated with modulation scheme determination for an unknown signal with noise are described. An unknown signal can have an unknown modulation scheme to a system. In order to determine a modulation scheme to use with the unknown signal, the unknown signal can be compared to a plurality of known signals, with an individual known signal being associated with a particular modulation scheme. A rapid classification method can be used that is less computationally intensive than an average likelihood ratio test method based on the distances between unknown symbols and constellation alphabets of a set of known modulation schemes. Signal to noise ratios before and after classification can be used to check an accuracy of classification and distribution of signal symbols can be used to verify a classification result.
