Abstract
Multilevelmodulations have good spectral efficiency, although at the expenseofpower efficiency. In mobile wireless systems, where there are strict powerandbandwidth constrains, we must maximize the power efficiency. This means the useofhigh-efficiencyamplificationschemes at the transmitter sideandcompact constellations combined with powerful equalizers at the receiver side. In this paper we considerSC-FDEschemes (Single-Carrier with Frequency-Domain Equalization) combined withmultilevelconstellations that can be decomposed as the sumofBPSK(Binary Shift Keying)signals. These components can be separately amplifiedandbesides this decomposition allows the definitionofnewefficientIB-DFE (Iterative Block Decision Feedback Equalization) implementations suitable formultilevelconstellations, with low impactonsystem complexity.
