Energy detection of multilevel PAM signals with systematic threshold mismatch

Research output: Contribution to journalArticleScientificpeer-review

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.
