Abstract :
A search procedure is developed to find good short binary (N,N - 1) convolutional codes. It uses simple rules to discard from the complete ensemble of codes a large fraction whose free distance d_{free} either cannot achieve the maximum value or is equal to d_{free} of some code in the remaining set. Farther, the search among the remaining codes is started in a subset in which we expect the possibility of finding codes with large values of d_{free} to be good. A number of short, optimum (in the sense of maximizing d_{free} ), rate-2/3 and 3/4 codes found by the search procedure are listed.
