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。
A New Decoding Algorithm for a Nonsystematic Convolutional Code in DPSK System 用于差分移相系统非系统卷积码的新译码算法
( 2,1,7) nonsystematic convolutional codes are optimal convolutional codes on the same code length and information bit length condition, so they are adopted as space standard codes by CCSDS ( Consultative Committee for Space Data Systems). (2,1,7)非系统卷积码在相同的码长和信息长度下为最佳卷积码,因此被CCSDS(空间数据系统咨询委员会)采纳为空间标准码。
