FIELD: information technologies. ^ SUBSTANCE: pulse enveloping a carrier wave for a specific M signal is generated and sent as proposed time functions, which depend on several parametres, which satisfy certain conditions of their selection. Variety of specified functions is stipulated for by the variety of versions of parametre sets. At the same time signals differ well from each other from the point of view of their detection. In the method groups of k bits are divided in the specified manner into subgroups, each with its parametre and appropriate number of bits selected so that their sum is equal to k. Subgroups are restored with substantially lower quantity of versions for each one, and then the whole group of k bits is restored using these subgroups in the specified manner. ^ EFFECT: improved efficiency of using frequency resource by increasing of number of bits send per clock cycle by M signals, and thus, volume of transferred information in the specified bandwidth, simplified realisation of information transfer and reception with M signals, better security of transferred information. |
