MODIFIED DEVICE FOR CORRECTING ERRORS Russian patent published in 2017 - IPC H03M13/43 

FIELD: physics.

SUBSTANCE: in the device containing four shift registers with switches, a decision block, a synchronizer with the corresponding connections, the fifth shift register with a switch, a code converter, the second decision block, a result generator with the corresponding connections are additionally entered. This allowed to expand the set of the decision rules on a limited amount of memory. The proposed set of the decision rules corrects errors in the symbols of the same name up to fourfold inclusive and fivefold errors. This leads to an increase in noise immunity, since the equivalent probability of distortion of a single symbol in the final combination decreases, which leads to a reduction in information loss.

EFFECT: increasing the noise immunity in the conditions of intensive influence of the interferences, leading to significant distortion of the same symbols when the message is repeated.
