Abstract :
Abstract-Non-binary low-density parity-check (NB-LDPC) codes can achieve better error-correcting performance than binary LDPC codes when the code length is moderate. In this paper, we give the different initial step for different modulation and present a hardware implementation of the extended min-sum (EMS) decoding algorithm for non-binary LDPC codes. Moreover, an FPGA simulation over GF(16) is given to demonstrate the efficiency of the presented techniques.
