An Optimized Method Based on Markov Chain to Calculate Total BER Pre-FEC

摘要

The simulation of COM only consider the random error. But the ratio of burst error to random error can represent the average error when burst error occurs, which is the key factor to analyze the BER Post-FEC. In this paper, the optimized method based on Markov chain is proposed for NRZ & PAM4 system. For NRZ system with multi-taps DFE, an alternative algorithm based on Markov chain is proposed. For PAM4 system, this algorithm can give the BER pre-FEC at each voltage level.
