Non-binary adaptive LDPC codes for frequency selective channels: code construction and iterative decoding
Joseph J. Boutros, Alaa Ghaith, Yi Yuan-Wu · 2006
We propose a new type of non-binary LDPC codes defined over multiple Galois fields. The so called multi-Galois LDPC code can adapt to the profile of a frequency selective channel and is suitable for multi-carrier transmissions with quadrature amplitude modulations
