ABSTRACT:
An error correcting scheme for processing data which is transmitted on a broadband and/or CATV network and utilizes the IEEE 802.4 three-level duobinary AM/PSK (phase shift keying) coding format. The error correcting scheme utilizes two thresholders. One of the thresholders makes data (1 or 0) decisions while the other thresholder makes non-data or no non-data (non-data) decisions. Pattern matching and windowing are used to detect non-data symbols which are corrected if the non-data symbols deviate from a predetermined pattern. The template used in the pattern matching is determined from the state of a demodulator.
