Max-log APP Detection for Non-bijective Symbol Constellations
arXiv:2102.04028
Abstract
A posteriori probability (APP) and max-log APP detection is widely used in soft-input soft-output detection. In contrast to bijective modulation schemes, there are important differences when applying these algorithms to non-bijective symbol constellations. In this letter the main differences are highlighted.
