FIELD: information technology. ^ SUBSTANCE: groups of Kn bits are split in prescribed orderly manner, corresponding to Kn synchronised binary digital streams, into subgroups with bits number in each subgroup selected so that sum of bits of all subgroups is equal to Kn, forming M1,n-symbols providing prescribed ordered bijective correspondence between these symbols and subgroups, and in subgroups providing bijective correspondence with bits versions in each subgroup, forming M1,n-signals with the same one envelope for all signals in subgroup, orthogonalisation of their envelopes and prescribed ordered bijective correspondence between signal subgroups and envelopes, forming specific Mn-signal as cluster of specific M1,n-signals. In this process, specific M1,n-signals are selected at receive from their cluster which has been transmitted in single tact, specific M1,n-symbols are obtained, relevant version is selected in each subgroup, and specific group of Kn bits is recovered in prescribed manner according to received versions. ^ EFFECT: higher data transmission effectiveness including providing necessary information capacity and range of coverage. |
