Patent ID: 8390484

Claim:
A transmitted/received data decoding method comprising: a coded edge patter filtering process for setting an intermediate pattern between an edge at a leading bit and an edge at a tailing bit of an original data of a predetermined number of bits as a coded edge pattern after analyzing coded patterns according to data coded characteristics, and filtering a received data by using the set coded edge pattern as a window; an absolute value computing process for respectively computing absolute values of filtered values filtered by the coded edge pattern filtering process using the coded edge pattern windows; an absolute value comparing process executed by an absolute value comparator for detecting a maximum absolute value from the absolute values computed by the absolute value computing process; a sign determining process for determining a sign for the maximum absolute value detected by the absolute value comparing process; and a decoded value outputting process for outputting an intermediate bit value of the corresponding original data as a resultant decoded value according to the determined sign determined in the sign determining process and a window type with the maximum absolute value selected in the absolute value comparing process.
