    This paper presents some multi-criterion concurrently-optimal (2, 1, 31) and (3, 1, 31) nonsystematic convolutional codes for sequential decoding. These codes are constructed with a computer using an algorithm of constructing nonsystematic convolutional codes found by Zhang Zhao-zhi. Some of convolutional code generators are given. The minimum distance dc(m) and column distance profile dc(0, h) of these codes are found to be optimal. The free distance d, of the (2, 1) code is made up to 29-30,...

    This paper presents some multi-criterion concurrently-optimal (2, 1, 31) and (3, 1, 31) nonsystematic convolutional codes for sequential decoding. These codes are constructed with a computer using an algorithm of constructing nonsystematic convolutional codes found by Zhang Zhao-zhi. Some of convolutional code generators are given. The minimum distance dc(m) and column distance profile dc(0, h) of these codes are found to be optimal. The free distance d, of the (2, 1) code is made up to 29-30, and of the (3, 1) code up to 47-49. All of the multi-criterion concurrently-optimal nonsystematic convolutional codespresented in this paper are intransparent with the greatest column inverse-distance dc(m) so that we. will be able to reduce the computational, requirements for recognizing the 180° phase-ambiguity in sequential decoding. The (3, 1, 31) nonsystematic code presented in this paper has concurrently-optimal performance for both 1/2 and 1/3 coding rates.

    本文根据章照止所提供的造码方法,用计算机构造了若干适用于序列译码的多准则兼优(2,1,31)和(3,1,31)非系统卷积码,并列出了部分码的生成元。其最小距离d_c(m)、列距离分布d_c(0,h)均达到最优。(2,1)码的自由距离d_f可高达29~30,(3,1)码的d_f达47~49。本文所列出的多准则兼优码全部是非透晰的。它还具有最大反列距离d_c(m)。因此在序列译码中使用后,将降低识别180°相位模糊度所需的计算量。本文列出的(3,1,31)非系统码具有1/2、1/3两种编码速率兼优的特性。
