METHOD OF TRANSMISSION OF MESSAGES OF ANY PHYSICAL NATURE, FOR INSTANCE, METHOD OF AUDIO REPRODUCTION, AND SYSTEM FOR ITS REALIZATION ( VARIANTS ), METHOD OF SPATIAL, ACTIVE REDUCTION OF LEVEL OF SIGNALS OF ANY PHYSICAL NATURE (VARIANTS )

摘要

FIELD: cybernetics, radio engineering, robotics, automotive industry. SUBSTANCE: method of transmission of messages of any physical nature in channel with interference consists in conversion of message to electric signals of message source, in multiband matched filtration of electric signals of message source, in multiband formation of signals for active interference reduction, in summing of these signals. in their amplification, in conversion of electric signals to signals of same physical nature, in emission of signals into channel ahead of message reception point, in reception and conversion of signal to received electric signal, in transmission of received signal to point of its processing, in processing of electric signals of message source and received electric signal. Conversion of electric signals to signals of any physical nature is performed on various frequencies, signals being emitted from various points of space. At least one emission point is placed closer to message reception point than others. EFFECT: increased accuracy of message transmission. 13 cl, 9 dwg
