КОДЕК ПОМЕХОУСТОЙЧИВОГО ЦИКЛИЧЕСКОГО КОДА |
摘要 |
FIELD: communications engineering; data transfer, telemetering, and telecontrol systems. ^ SUBSTANCE: proposed codec has on sending end code-word data part shaper whose output and that of code-word synchronizing part shaper are connected to modulo two adder input; on receiving end it has binary filter whose code-word data part shaper output is connected to accumulator connected to synchronizing sequence decoder and to error connection unit whose outputs are connected to respective inverting inputs of code-word data part shaper; output of the latter functions as data output of device; output of binary-filter code-word synchronizing part is connected through switching unit to input of code-word data part shaping unit; synchronizing sequence decoder output is connected to control input of switching unit and to error correction unit input; on receiving end accumulator outputs are connected to inputs of code-word data part shift decoder whose output is connected to input of delay circuit whose output functions as second control input of switching unit and as synchronizing output of device. ^ EFFECT: enhanced noise immunity. ^ 1 cl, 1 dwg |
