Abstract :
The turbo code performance over time-varying channels using QPSK modulation is evaluated in this paper. For this purpose we have considered a block random in line (BRL) interleaver. On the basis of this interleaver, we have further simulated the turbo code performance over Rice flat fading channel using 15 iterations. Also, we have studied the impact of the estimation error in the calculation of the channel log-likelihood ratios Lc.
