Abstract:

The undetected error probability of linear block codes for both error detection and correction is estimated with importance sampling. Formulas for optimum bias transition probability and simulation efficiency are obtained theoretically. Simulation results for the (15,7) BCH code and the (23,12) Golay code show that the importance sampling is a very efficient method.
