High‐Rate Punctured Convolutional Codes

Abstract

This paper investigates high rate punctured convolutional codes suitable for Viterbi and sequential decoding. Results on known short constraint length codes (K<10) discovered by others are extended. Weight spectra and upper bounds on the bit error probability of the best known punctured codes having constraint lengths 3<K<9, and coding rates 2/3<R<7/8 are provided. Newly discovered rates 2/3 and 3/4 long constraint length punctured convolutional codes with 10<K<23y are provided together with the leading terms of their weight spectra and their bit error performance bounds. Some results of simulation with sequential decoding are given. HIGH-RATE PUNCTURED CONVOLUTIONAL CODES
