Abstract :
This paper proposes an importance sampling design for the codeword error rate estimation of low-density parity-check codes. An error set partitioning method is introduced to reduce the error boundary complexity and to improve the simulation efficiency. This is a follow-up to the work in (B. Xia et al., 2003).
