FIELD: exchange of discrete information with use of communication systems with various types of modulation. SUBSTANCE: technical result of invention consists in transmission to user of information on authenticity of signal belonging to specific signal region, on quality of through discrete communication channel, in optimization in process of reception of dimensions and configuration of uncertainty zones depending on quality of communication channel. In correspondence with invention method reconstructing transmitted information signals after passage through communication channel identifies signal regions, uncertainty zones and characteristic zones, signals received in analog form are divided into orthogonal components by correlation method, belonging of received signal to particular signal region, to uncertainty zone and characteristic zone is determined in the form of its numbered orthogonal components. EFFECT: transmission of authentic information to user. 4 dwg
