The new type of the communication system using for information transfer of value of invariants of groups of transformations, characterizing a communication channel is considered. The noise stability of two methods of calculation of estimations of information elements is investigated: a method of direct division of estimations of lengths of vectors of information and basic signals and a method of the maximum credibility in a combination to accumulation of estimations of lengths of vectors of basic signals.
