摘要：This paper describes the use of Karhunen-Loeve transform (KLT) for the modulation recognition in HF and VHF bands. The input real signal is pre-processed and converted to the "phase image". The KLT is applied and the dimensionality reduction is implemented and the classifier recognized the signal. The method clustering analysis was chosen by acclamation for 3-class recognition of 2-FSK,4-FSK and PSK signals. The 3-class minimum-distance classifier of modulation was created in the programme Matlab. The tests of designed algorithm were implemented on real signal patterns.
