Abstract
Maximum likelihood sequence detection (MLSD) of digital signaling subject to intersymbol interference (ISI) and additive white Gaussian noise (AWGN) is considered. A new and simple bit error probability bound is obtained
especially for the low and high SNR regions. In addition
in the case of infinite-length ISI
the performance loss due to the ISI tends to zero for physical channels.
