T1 Problems of Design of Information Systems at the Signal Level JF Telecommunications and Radio Engineering JO TRE YR 2007 FD 2007-10-17 VO 66 IS 10 SP 883 OP 897 AB The methodology of design of information systems at the signal level, which takes into consideration multidimensional semistructured expert information, is discussed. The theory of fuzzy sets is used to describe the methods for optimization of the efficiency of designed radio engineering information systems solving the problems of signal detection and recognition.
