A device for detection and correction of errors in a signal, 1984, in a bipolar code

摘要

This device comprises: - a recursive equaliser 24 with two-level detection, the said equaliser receiving a bipolar signal Sr comprising a succession of bipolar symbols b, i, and delivering a two-level signal @ composed of a succession of estimated binary symbols @, i, and an error signal E, - an error detector 26 comprising two threshold comparators, the said detector receiving the error signal E and delivering a binary error signal EP representative of the errors in detection of the symbols @, i, - a transcoder 28 receiving the signal @ and delivering a binary signal d composed of a succession of symbols @, i which, in the absence of detection errors, are identical to the binary symbols d, i corresponding to the symbols b, i transmitted.
