DECODER WITH ENHANCED LEVEL OF RELIABILITY ESTIMATE IDENTIFICATION Russian patent published in 2003 - IPC

FIELD: communications engineering; designing novel digital data transmission systems and updating existing ones. SUBSTANCE: device has receiving unit whose output is connected to input of signal analyzer; stacker whose output is connected to erase recovery unit whose first output is connected to control input of stacker and second output, to one of inputs of erase correction unit; other input of the latter is connected to other output of receiving unit. Newly introduced in device are adder, erase unit, and additional signal analyzer; input of erase unit and that of additional signal analyzer are connected to receiving unit output; outputs of signal analyzer and additional signal analyzer are connected to first and second inputs of adder, respectively; erase unit output is connected to subtracting input of adder whose output is connected to stacker input. EFFECT: enhanced reliability of erase and error recovery in code chain. 1 cl, 1 dwg
