METHOD OF SUPPRESSION OF CROSS-TALK INTERFERENCES IN MULTIWIRE COMMUNICATION LINES Russian patent published in 2016 - IPC H04B3/32 

FIELD: electricity.

SUBSTANCE: in communication lines with n wire pairs two units with n transformers are used, each of which contains primary and n secondary windings. The signal sources and/or recipients are connected to primary windings of transformers, and secondary windings of transformers are connected to inputs and outputs of switches which can be connected in series, opposite, or not to connect corresponding pairs of inputs and outputs of one side to outputs/inputs of another side. The internal architecture of switches for odd number of wire pairs is defined by elements of Belevich matrix with the dimension n, and for even number of wire pairs it is defined by value of elements of Hadamard matrix with the dimension n. The multiwire communication line is connected to outputs/inputs of switches. Advantages of the offered method include reduction of cross-talk interferences, increase of range and speed of data transmission, and also improvement of stealthiness and simplification of manufacture of multiwire cables.

EFFECT: possibility of suppression of cross-talk interferences in multiwire electric cables with any number of wire pairs.
