FIELD: information technologies. ^ SUBSTANCE: signal pulses are generated and sent in the form of proposed time functions, depending on several parametres, which meet certain conditions of their selection. Variety of the specified functions is specified by variety of parametre sets versions. At the same time the signals differ well from each other from the point of view of their recognition. Besides, with the fixed value of one of parametres, signals are transferred with the identical energy per cycle. In method, groups of k bits are subdivided into subgroups, with a parametre corresponding to each of them, as well as a corresponding quantity of bits selected so that their sum is equal to k. When recovered during reception, subgroups c are recovered stage by stage, and then, using these subgroups, the whole group of k bits is recovered. ^ EFFECT: increased efficiency of using frequency resources by increasing quantity of bits sent per cycle with M signals, and thus increased volume of transferred information in the specified frequency band, simplified realisation of information transfer-reception by M signals, improved security of transmitted information. |
