DECODING DEVICE FOR NOISE-IMMUNE VARIABLE-LENGTH CONCATENATED CODE Russian patent published in 2007 - IPC H03M13/35 

FIELD: electrical communications; digital data transfer systems for decoding noise-immune variable-length concatenated code.

SUBSTANCE: proposed decoding device for noise-immune variable-length concatenated code has buffer memory and frame synchronization unit; their inputs are integrated to function as information input of device; outputs of buffer memory and frame synchronization unit are connected to internal-code decoder whose output is connected to external-code decoder; output of the latter functions as information output of device; newly introduced in device are time interval shaper, code word counter, and analysis unit; synchronization input of device is connected to input of time interval shaper whose control input is connected to output of frame synchronization unit; output of time interval shaper is coupled with inputs of code word counter and analysis unit whose other input is connected to output of code word counter whose synchronization input is coupled with internal-code decoder; output of analysis unit is connected to external-code decoder.

EFFECT: enhanced noise immunity of decoding device.
