| Abstract: | A novel systematic and irregular generalized low-density code with zigzag component(ZS-IGLDPC) was pro-
posed in this paper. hhe sequences of degree distribution was designed by Gaussian approximation based density evolu-
lion under the additive Gaussian white noisy channel. The performance of ZS-IGLDPC was analyzed by simulation. The
simulation results show that the bit error rate of ZS-IGLDPC codes is less than other available codes for short and medi-
um code length. |
