METHOD AND DEVICE FOR ESTIMATING QUALITY OF DATA-TRANSMISSION CHANNEL Russian patent published in 1997 - IPC

FIELD: electric communications; on-line inspection of data-transmission channel for quality. SUBSTANCE: method involves reception of code combinations, their decoding including syndrome separation, determination of increment to error counter readings, error addition based on syndrome identification with reference values written in storage units. Device implementing this method has decoder 1, increment measurement unit 2, error counter 3, clock synchronizer unit 4, clock pulse divider 5, and code combination counter 6. EFFECT: improved accuracy of data-transmission channel quality estimation and reduced inspection time due to using noise-immune code for error detection and correction in syndrome decoding. 9 cl, 9 dwg
