METHOD FOR TRANSFERRING A MESSAGE OF ANY PHYSICAL NATURE, FOR EXAMPLE A METHOD FOR SOUND MESSAGE TRANSFER AND SYSTEM FOR CARRYING OUT SAID METHOD (VARIANTS). METHOD FOR ACTIVE SPATIAL REDUCTION OF AMPLITUDE LEVELS OF ANY PHYSICAL VARIETY (VARIANTS)

摘要

The inventive method for transferring a message consists in the following: the multiband matched filtered electrical signals of the source and multiband formed signals for active noise reduction are combined for multiband message transmission on corresponding bands. The number of combined signals is not less than two; each combined signal of the corresponding frequency band is amplified, transformed into a signal of the same physical nature and emitted from various points in space to the circuit. At least one of the emitting points of any physical variety is placed nearer to the receiving point than the other points. The inventive method increases the accuracy of the information transfer through channels which have low-modified parameters relating to the distance between the emitting and receiving points, and whose noise has, in principle, uncertain and random parameters.
