Abstract :
A new formula is derived to compute the codeword weights of rate 1/n convolutional codes. This formula allows us to derive a new asymptotic lower bound on the row distance that surprisingly reaches the upper bound on free distance in the limit of large memory m. This formula also leads to a new approach for constructing finite constraint length convolutional codes.
