Abstract:
Considers the problems of quasi-orthogonal signals ensembles designing with many transformation options for increased structural stealth async-address radio systems. The first one is generated by the desire to create the greatest ensemble for the acceptable level cross-channel interference having constraints on the time of the signal acquisition and on the complexity of respective devices implementation. These characteristics strongly depend on the considered class of signals, so one is fixed when the best ensemble is designed. The second problem occurs when exposed to imitation interference, effective protection from which is to enhance structural stealth radio systems by periodic change of the used ensemble of signals [1] in the class. A separate task is to design of signals in which under these constraints these problems are solved in the best way. The article, based on the algebraic representation of cross-correlation function of M-sequences and other algebraic codes, the model of signal ensembles designing with many transformation options to increase of structural stealth async-address radio systems under the influence of noise and imitation interference is proposed.
