Abstract :
An existing sequential decoding program can be easily modified to enumerate the number of low-weight codewords in a convolutional code, where weight is defined either over a decoding constraint length or "free." We tabulated several good rate one-half constraint-length 49 systematic codes that were obtained quickly with this procedure.
