This paper presents a statistical modeling approach to accurately estimate post-FEC BER for high-speed wireline links using standard linear block codes, such as the RS(544,514,15) KP4 and RS(528,514,7) KR4 codes. A hierarchical approach is adopted to analyze the propagation of PAM-symbol and FEC-symbol errors through a two-layer Markov model. In this paper, we will turn our proposed BER estimation method into a set of tools to assist in making architectural choices for wireline transceivers, such as co-design of the equalization and FEC in the presence of DFE error and various noise sources including residual ISI, crosstalk, transmitter and receiver jitter.

Takeaway

A statistical modeling approach to accurately estimate post-FEC BER below 10^-15 for high-speed wireline links using standard linear block codes while accounting for DFE error propagation and other noise sources including residual ISI, crosstalk and TX/RX jitter.

Intended Audience

Basic knowledge in probability and statistics; familiar with common equalization techniques in wireline Serializer/Deserializer; understanding the fundamentals of linear block codes
