本文研究了混合长度的删位纠错码的构造问题.利用组合设计的方法构造了长为{3,4,5)的完备删位纠错码T(2,{3,4,5),v),当v为正整数且v≠8时,得到了所有的T(2,{3,4,5),v)-码,并给出码字总数的一个上界,T(2,{3,4,5},v)-码的构造推广了长度为单一值的删位纠错码的构造结果.
In this paper, deletion codes of mixed length are considered. For all positive integers v except v = 8, T(2, {3,4, 5}, v)-codes are constructed by means of TD and GDD. The bound of T(2, {3, 4, 5}, v)-codes is also investigated. T(2, {3, 4, 5}, v)-codes are the generalization of perfect deletion-correcting codes of single fixed length.
