Constructions of regular and irregular LDPC codes using Ramanujan graphs and ideas from Margulis
Joachim Rosenthal, Pascal O. Vontobel · 2002
Some twenty years ago Margulis (1982) proposed an algebraic construction of low density parity check (LDPC) codes. In this paper we mimick the construction of Margulis and describe a method for algebraically constructing regular and irregular LDPC codes.
