Non-uniform 2-slot constellations: Design algorithm and 2-way relay channel performance
Popis výsledku v původním jazyce
Performance of Wireless-Network-Coding-based relaying strategies for 2-Way Relay Channel (2-WRC) could be seriously degraded due to an inherent wireless channel parameterization. Although some techniques dealing with this problem have been already introduced, they are still subject to several drawbacks (including a practical infeasibility of multi-node transmission phase pre-rotation or a sensitivity to channel estimation errors of adaptive solutions). Unfortunately, this detrimental channel parameterization effect endures even when the relay has perfect channel state information available. Based on the analysis of hierarchical minimum distance of source constellation alphabets, in this paper we target this problem from a different way. We propose a design of novel source constellation alphabets, the Non-uniform 2-slot (NuT) alphabets, which are robust to channel parameterization effects. These NuT constellations outperform traditional linear modulation schemes in Hierarchical-Decode-a
