Abstract :
When estimating the bit error rate (BER) of communications systems using Monte Carlo (MC) simulation, importance sampling (IS) may be a powerful method for reducing simulation runtimes. The paper presents an IS technique combined with error event simulation in order to evaluate efficiently the performance of Viterbi decoding used with a binary nonsymmetric channel and with a binary erasure channel. Two biasing approaches are employed, stationary and nonstationary models. Comparative results between the two models and traditional MC methods are presented.
