FIELD: information technology. ^ SUBSTANCE: pulse, which envelopes the carrier wave for a specific M-ary signal is generated and transmitted in form of proposed time functions which depend on several parameters which satisfy defined conditions for their selection. The variety of said functions is a result of the variety of versions of sets of parameters which enable transmission of large amounts of information. When receiving signals, their parameters are well distinguished and a situation for transmitting signals with constant energy in cycles is realised. The method is characterised by division of a group of k bits into subgroups in a certain way, each subgroup corresponding to its own parameter and the corresponding number of bits, selected such that their total is equal to k. Restoration during reception of a specific group is simplified, since at the beginning, subgroups with significantly fewer versions for each are restored step-by-step and the entire group of k bits is then restored based on these subgroups in a defined way. ^ EFFECT: high efficiency of using a frequency resource by increasing the number of bits transmitted in one cycle by M-ary signals, amount of the transmitted information, as well as secure transmission of information. |
