一类小缺陷码的链条件
The Chain Condition of a Kind of Code of Small Defects
摘要
利用射影几何方法在小缺陷码中,NMDS码是链条件码;给出k维NμMDS(0μk-2)码满足链条件的一个充要条件与一些易判断的充分条件.
NMDS codes are all the ones satisfying the chain condition; An equivalent condition and several sufficient conditions are given for N^μMDScodes （0≤μ≤k-2） to sectisfy the chain condition by finite projective geometry method.
