This paper presented a method for constructing NB-QC-LDPC (non-binary quasi-cyclic LDPC) codes. First, the initial base matrix of NB-QC-LDPC code was constructed by two arbitrary subsets in a finite field. Then, by combining the number and connectivity of cycles jointly, the new masking method was proposed to construct a type of NB-QC-LDPC codes with larger ACE average values. The simulation illustrates that proposed codes have better error correction performance compared with binary LDPC codes and other NB-LDPC codes.
