扩展码
延伸码
Examples
- Absolute minimal trellis complexities of extended codes and their dual codes of two types of linear block codes whose code length is odd are given
给出了两类奇数码长线性分组码的扩展码及其对偶码的绝对最小网格图复杂度。 - As to cyclic codes over finite chain rings , we study their stucture and develop the fourier transform method to finite chain rings . the permutation groups of cyclic codes and their extended codes are investigated using their mattson - solomn polynomials
对于有限链环上的循环码，我们研究了它们的结构，并把傅立叶变换的方法推广到有限链环，用循环码的mattson - solomn多项式对循环码及其扩展码的置换群进行了研究。 - The concept of good codes and proper codes for both error detection and correction is presented . it is shown that the binary perfect codes and the primitive double - error - correcting bch codes and their extended codes are proper for both error detection and correction . the primitive triple - error - correcting bch codes with length 2 " " - 1 and their extended codes are proper for odd m > 5 , not for even m > 6
本文的主要工作是把目前关于只检错时线性码不可检错误概率的研究推广到同时纠错和检错的情况，获得了同时纠检错时线性码不可检错误概率的解析表达式，提出了纠检错好码和最佳纠检错码的概念，并证明了二进制完备码及其扩展码是最佳纠检错码；纠正两个错误二进制本原bch码及其扩展码是最佳纠检错码；码长n = 2 ~ m - 1 、纠正三个错误本原bch码，当m为大于等于5的奇数时是最佳纠检错码；当m为大于等于6的偶数时，不是最佳码。
