Design of constellations for adaptive minimum-cardinality PLNC 2-way relaying utilising the symmetry of hexagonal lattice.

Popis výsledku v původním jazyce

This paper targets a constellation design for adaptive physical-layer network coding strategy in a wireless 2-way relay channel. The relay requires an extended cardinality network coding adaptation to avoid all singular channel parameters at the Multiple-Access (MA) stage if the terminals are using standard 4QAM constellations. The cardinality extension is undesirable since it introduces redundancy decreasing the data rates at the broadcast stage. We focus on a design of constellations avoiding all thesingularities without the cardinality extension. We show that such a constellation is 4-ary constellation taken from hexagonal lattice (4HEX) which keeps comparable error performance at the MA stage as 4QAM, however without the cardinality extension. Thesimilar properties has been found also by unconventional 3HEX and 7HEX constellations.
