Abstract
In this paper, we address a symbol decision problem with spectrally
efficient energy detected multilevel pulse amplitude modulated (PAM) signals.
First we analytically quantify the relationship between a systematic threshold
mismatch and the required increase of the average signal-to-noise ratio to
preserve a desired symbol error rate. For the case in which such an increase
is not tolerable, we present a novel near-optimal multilevel threshold
selection scheme, which is accurate for a wide range of system parameters.
