ABSTRACT:
In a Viterbi decoder for use in producing a decoded signal by correcting and decoding convolutional codes, a majority circuit (46) is connected to a path memory (45). At each of the time slots used for the respective convolutional codes, the majority circuit makes a decision and selects a decoded datum of the decoded signal in response to a majority of information bits which are memorized in the path memory. The Viterbi decoder consists of a read-only memory, which simplifies the circuit, reduces the required number of circuit elements, and makes a lower cost circuit.
