METHOD AND DEVICE TO IDENTIFY CLASSES OF SIGNALS Russian patent published in 1999 - IPC

FIELD: radio engineering, automatics and technical diagnostics of parameters of signals, design of automatic identification systems for complexes of technical analysis and identification of classes of signals. SUBSTANCE: method identifying classes of signals consists in reception of Q realizations of signals, in their memorizing and in finding of events called inhibited on basis of their processing, in counting of their total number S and in comparison of computed value with preset threshold one S_n. Provided condition S <S < S_n is realized signal is identified as one having CKK with lattice coding. Device to identify classes of signals has address former 1, storage 2, unit 3 determining inhibited events, unit 4 making decisions. Former 1 controls memorization and reading of realizations received by storage 2. Storage 2 memorizes realizations for time of analysis and sends two groups of realizations to unit 3 under control of former 1. Unit 3 detects inhibited events by comparison of these two groups of realizations, by selection of variants when one pair only in pair of groups does not coincide and by comparison of least significant positions of realizations in this pair. Unit 4 counts number of inhibited events, control process of analysis and makes decision on presence of CKK with lattice coding in signal. EFFECT: development of method and device identifying classes of signals which provide for possibility of recognition of SCC with lattice coding and do not complicate at same time design of device that realizes given method. 8 cl, 9 dwg
