<p>The conventional serial estimating method using the viterbi algorithm is changed in the following way: (1) a changed path which is obtained by changing the route of a path a specific time past is led out, (2) the path metric value of the changed path is calculated, (3) the path metric value of the changed path is compared with that of a normal path and, when the path metric value of the changed path is smaller, the route of the changed path is corrected, and (4) a surviving path is selected out of a plurality of paths passing the corrected route.</p> |
