q元非线性2-重量码(n,2,ω_1,ω_2)的检错性能

q-ary 2-weights (n,2,ω_1,ω_2) Codes for Error Detection

通过定义δ(xi,yi)函数,把2元非线性2-重量码(n,2,ω1,ω2)的性质推广到q元非线性2-重量码(n,2,ω1,ω2)上,根据码的距离分布和对偶距离分布讨论了码C的不可检错概率.给出了码C不是最佳检错码的几个条件.

In this paper, By definition δ（xi,yi） function, Binary weights （n,2,ω1,ω2） codes is generalized to q-ary weights （n,2,ω1,ω2） codes, Be based on distance distribution and Dual distanee distribution of codes, to discuss several condition of the code being proper code.
