Abstract :
In this paper, we propose an enhanced min-sum decoding algorithm for DVB-T2 LDPC codes. It is obtained by two step approximation of the function ln cosh(x) on the sum-product algorithm. Simulation results show that the proposed algorithm does not cause serious performance degradation, as compared with sum-product algorithm. In addition, it shows better performance than conventional min-sum algorithm and its modifications.
