基于多项式的剩余类环理论,给出了magnitude错误标准下m元可纠小于等于t个非对称错纠错码的构造方法.由此构造方法给出了这类码码字个数的下界.
Based on residue rings of polynomials, a general construction of rn-ary codes of correcting t or fewer asymmetric error with the magnitude error criterion is presented. Some lower bounds for such codes are obtained from this general construction.
