IEEE Transactions on Communications, 1990•ieeexplore.ieee.orgThe weight spectra of high-rate lpunctured convolutional codes are evaluated under the
hypothesis of a low-rate structure. This interpretation yields results slightly different from
those obtained when weight spectra are evaluated assuming a true high-rate structure for
punctured codes. The search for long memory punctured codes is extended by providing
new punctured codes of rates 4/5, 5/6, 6/7, and 7/8 with memories ranging from 9 to 19.<>
