  • Abstract
    We present rational rate k/n punctured convolutional codes (n up to 8, k=1, ···, n-1, and constraint length ν up to 8) with good performance. Many of these codes improve the free distance and (or) weight spectra over previously reported codes with the same parameters. The tabulated codes are found by an exhaustive (or a random) search
