Nonbinary multiple rate QC-LDPC codes with fixed information or block bit length
Lei Liu, Wuyang Zhou, Shengli Zhou · Journal of Communications and Networks · 2012
In this paper, we consider nonbinary quasi-cyclic low-density parity-check (QC-LDPC) codes and propose a method to design multiple rate codes with either fixed information bit length or block bit length, tailored to different scenarios in wireless applications. We show that the proposed codes achieve good performance over a broad range of code rates.
