FIELD: telecommunications.
SUBSTANCE: invention relates to telecommunication and can be used to transmit audio broadcast signals in analogue and digital communication channels. Result is achieved by generating on the transmitting side an auxiliary information audio broadcast signal from the main information audio broadcast signal, which exactly corresponds to main information audio broadcasting signal. In said main and auxiliary broadcast signals, due to multiple and identical processing, the same noise and distortions occur. Then, not processed and undistorted broadcast transmission signal is subtracted from distorted auxiliary broadcasting signal. Interference and distortions of the transmitting and receiving sides thus determined form a pre-distortion signal, which is further inverted in phase and input into the main undistorted broadcast transmission signal and obtaining the main pre-emitted broadcasting broadcast signal. By means of this main pre-emitted broadcast transmission signal, interference and distortions caused by processing in the broadcasting signal at the transmitting and receiving sides are compensated. Due to such compensation of noise and distortions it is possible to significantly improve quality of audio broadcasting signals transmission. Higher quality of audio broadcast signals allows reducing transfer rate or volume of signal during its transmission and storage.
EFFECT: technical result is high quality of transmitting audio broadcast signals.
