Abstract:
While channel coding is a standard method of improving a system’s energy efficiency in digital
communications, its practice does not extend to high-speed links. Increasing demands in network speeds
are placing a large burden on the energy efficiency of high-speed links and render the benefit of channel
coding for these systems a timely subject. The low error rates of interest and the presence of residual
intersymbol interference (ISI) caused by hardware constraints impede the analysis and simulation of coded
high-speed links. Focusing on the residual ISI and combined noise as the dominant error mechanisms, this
paper analyses error correlation through concepts of error region, channel signature, and correlation
distance. This framework provides a deeper insight into joint error behaviours in high-speed links, extends
the range of statistical simulation for coded high-speed links, and provides a case against the use of biased
Monte Carlo methods in this setting
