Method and apparatus for decoding transmitted/received data

The present invention discloses a transmitted/received data decoding method and apparatus, which achieve effects of decoding performance improvement and synchronous detection. The decoding method includes setting a coded edge pattern, and filtering a received data by using the set coded edge pattern as a window; respectively computing absolute values of filtered values filtered by using the coded edge pattern windows; detecting a maximum absolute value from the computed absolute values; determining a sign (+/−) for the detected maximum absolute value; outputting an intermediate bit value of the corresponding original data as a resultant decoded value according to the determined sign and a window type (i.e. coded edge patter) with the selected maximum absolute value.
