“…Note that this was expected, since the matrix multiplication in (4) is actually a matched filtering [1], [33], [34]. Reminiscent of the notation used for ISI channels which, as shown in the following, is a particular case of the very general model (1), we will call y and x as Forney and Ungerboeck observation models, respectively [33], [34]. The system model corresponding to (1) is…”

“…In [9,2], a lower bound was derived on the symbol error probability achieved by the Viterbi equalizer for an ISI channel when no a priori information is available. By following the reasoning of [9,2], we can derive expressions of tight lower bounds on the BER of the a posteriori LLRs at the output of the MAP sequence equalizer when it is fed with a priori LLRs.…”

“…The decoder is therefore called the genie decoder. The main motivation for us to investigate the genie decoder is to get a BEP performance lower bound, since the genie-aided decoding should outperform these without a genie aid [29]. Also, as we will show, the performance bound for the genie decoder is quite straightforward to evaluate, and it is tight for practical BEP regions (below 10 −2 ).…”
