<p>PATH TRACE VITERBI DECODER A path trace viterbi decoder comprising an ACS circuit for generating a path selecting signal, a path memory for storing the path selecting signal, a node calculator for calculating the node number of a most memory for storing the path selecting signal, a node calculator for calculating the node number of a most likely path on the basis of the data read out from the path memory, and a trace memory for storing the most likely path data, etc. The node number data of the most likely path calculated by the node calculator is stored in the trace memory and the decoding operation is carried out by using the data read from the trace memory.</p> |
