【摘要】 多重级联奇偶校验码其编码相当简单,参数选取灵活,在译码复杂度很低情况下能够取得接近香农容量极限的性能。卷积码,作为基本编码技术之一,已广泛应用在各种数字通信系统中。本文通过仿真显示,在高斯白噪声信道下,串行多重级联奇偶校验码或串并混合的多重级联奇偶校验码能够获得比卷积码更佳的性能。更多还原

【Abstract】 With considerablely simple encoding and flexible code parameters,multiple concatenated single parity- check(SPC)codes can provide near Shannon limit performance at very low decoding complexities.Convolutional codes,as one of primary coding techniques,have been widely used in various digital communication systerms.In this paper,it is shown by simulation that multiple serial concatenated SPC codes or hybrid concatenated SPC codes are capable of outperforming traditional convolutional codes in additive white Gaussian channels.更多还原
