Parameter-Invariant Hierarchical Exclusive Alphabet Design for 2-WRC with HDF Strategy	2010	8	.pdf	application/pdf	5177	238	59	Significant capacity degradation is caused by channel parametrization, which highlights the importance of HXA design resistant to channel parametrization. The proper design of HXA is important, especially in the case of parametric channels, where channel parametrization (e.g. phase rotation) can violate the exclusive property of hierarchical symbols (as seen by the relay), resulting in significant capacity degradation.	cache/ap-1245.pdf	txt/ap-1245.txt
