Abstract: This paper provides a comprehensive analysis of nonbinary low-density parity check (LDPC) codes built out of protographs. We consider both random and constrained edge-weight labeling, and ...

Abstract: In this paper, we study the relationships between the girth of the Tanner graph of a quasi-cyclic (QC) protograph low-density parity-check (LDPC) code, the lifting degree, and the size and ...

Physicists at the University of Oxford have demonstrated a fundamentally new family of quantum cat states — quantum superpositions whose individual components are not the smooth, near-classical wave ...
