Abstract

We reconsider the minimum/optimal bit-error
probability receiver (OBER) for intersymbol interference
channels with Gaussian noise and the reception of finite
b1oc:ks of bits. We view the OBER as a function with
two inputs: the received sequence and an expected signalto-
noise ratio; and one output: the estimated block of
bits. Assuming that all sequences are equally probable to
be t.ransmitted we prove two results about the behaviour
of the QBER. We show that the QBER coincides with
the maximum likelihood sequence detector when designed
for high signal-to-noise ratios and that it collapses to a
matched filter followed by a hard-limiting device for low
expected signal-to-noise ratios.
