Název v původním jazyce

Classifiers of Digital Modulation Based on the Algorithm of Fast Walsh-Hadamard Transform and Karhunen-Loeve Transform

Popis výsledku v původním jazyce

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