TurboCode bit error rate (BER) performance with DRP interleaving

  • M=8 and K=1504 data bits (188 bytes, MPEG block size)
  • Measured minimum (Hamming) distance for this DRP interleaver is 76.
  • Code rates are R=1/3 (unpunctured) and R=2/5, 1/2, 3/5, 2/3, 3/4, 4/5, and 6/7 (punctured).
  • 16-state TurboCode, modified max-log-APP, polynomials
    (23,35)8, dual termination, early stopping, maximum iterations=16.
