IPC: H04L27/22
Filed: 1996-12-04
Abstract: PROBLEM TO BE SOLVED: To provide a viterbi decoding circuit whereby the encoding gain of viterbi decoding is obtained only by the orthogonal wave detection of 0 deg./90 deg. without adding a unique word. SOLUTION: A data converting part 4 is provided with a coordinate conversion table together with the table of branch metric generation so as to execute shift rotation for removing phase non-establishment based on the output of a node judgement control part 8 by using the coordinate conversion table. Viterbi decoding is executed against data outputted from the data converting part 4 by an addition comparing circuit 5, a pass memory part 6 and a most likelihood judging part 7. Two-bit data with excellent S/N within output three bits is viterbi-decoded and data of the remaining one bit is decoded by the value. Thus, a circuit incidental to 45 deg. and its orthogonal wave detection is unnecessitated.
