New good rate-P/(P+δ) rate-compatible punctured convolutional (RCPC) codes for 2 ≤ P ≤ 7 and 1 ≤ δ ≤ (n-1)P were found and tabulated. These codes have been determined by iterative search based upon a criterion of maximizing the free distance and were generated by periodically puncturing their rate-1/n mother codes of memory 2 ≤ M ≤ 6 and n = 2. These codes are expected to find their applications in unequal error protection schemes employing Viterbi decoding.
