Abstract :
This paper presents a memory efficient decoding algorithm for the non-binary low-density parity-check (NB-LDPC) codes. Compared to other recently developed Min-Max decoding algorithm, the message memory as well as the average number of iterations has been reduced using the proposed decoding method. Meanwhile, the corresponding decoder architecture is also proposed.
