Abstract :
This paper introduced a construction for LDPC codes over GF(q) based on filling with circulant matrices. After expanded the cycles in the check matrix by filling circulant matrices, the error-correcting performance of the codes can be improved with a low constructing complexity. The simulation results shows that the codes constructed can achieve better error-correcting performance.
