FIELD: technology for transmitting and receiving digital information.
SUBSTANCE: in accordance to the method during transmission a set of data bits, meant for transmission, is generated in a set of protocol data blocks, header bits are inserted into distributed positions within limits of protocol data blocks, where header bits are shifted relatively to one another, and protocol data blocks are used to modulate a set of carriers, generating the output signal. During receipt of digital signal of audio radio broadcasting, protocol data blocks are demultiplexed and transformed to audio signal of main program service and integrated signal of data transmission service, which are transformed to outgoing audio signal and outgoing data signal.
EFFECT: increased dynamic range in digital audio radio broadcasting system, and reduced noise in transmitted signal.
