FIELD: digital communications, namely, devices for selecting component streams (user data channels) in digital information transfer systems with temporal multiplexing. ^ SUBSTANCE: in accordance to method one demultiplexing device ensures various non-standardized digital transfers of information, named radio cycles, which contain a portion of symbols of user data channel, and also checking or service symbols, and in which synchronization group is absent, with various types of phase and quadrature-amplitude modulation. For this purpose demultiplexing device contains adjustment device, first random-access memory device, first signal adjuster, code transformer, modulus K adder, data channel setup device. Invention introduces divider in two, AND element, first counter, decoder, second signal adjuster, clock remover, second counter, second random access memory device. ^ EFFECT: expanded functional capabilities. ^ 4 dwg |
