CODE SEQUENCE RECOVERY DEVICE Russian patent published in 2005 - IPC

FIELD: communications engineering.

SUBSTANCE: proposed device that can be used for developing new and updating old digital-information transmission systems has receiver unit one of whose outputs is connected through signal analyzer to accumulator, one output of the latter being connected to first input of deletion recovery unit whose information output is connected to one of inputs of deletion correction unit. Newly introduced in device are code combination accumulator, demodulation evaluating unit, and correction unit whose output is connected to second input of deletion recovery unit whose control output is connected to second input of correction unit; first input of the latter is connected to output of demodulation evaluating unit whose first input is connected to other output of accumulator and second input, to second output of code combination accumulator; input of the latter is connected to other output of receiver unit and first output, to other input of deletion correction unit.

EFFECT: enhanced reliability of deletion recovery and error correction in code sequence.
