NOISE-IMMUNE CYCLIC CODE CODEC Russian patent published in 2005 - IPC

FIELD: communications engineering; network remote measuring and control systems.

SUBSTANCE: proposed noise-immune cyclic code codec designed for data transfer without pre-phasing has on sending end code-word information section shaper incorporating shift-register memory elements, units for computing verifying parts of noise-immune code of code-word information section, and modulo two adder of code-word information section shaper; code-word synchronizing section shaper and modulo two adder of code-word synchronizing section; on receiving end it has binary filter incorporating binary-filter shift register memory elements, computing units for verifying parts of binary-filter noise-immune code, and binary-filter modulo two adder; shift register of code word information section; decoder; accumulator; error correction unit; unit for shaping synchronizing section of code word; and modulo two adder units.

EFFECT: enhanced speed of device.
