Determining the Complete Weight Distributions of Some Families of Cyclic Codes
摘要
Obtaining the complete weight distributions for nonbinary codes is an even harder problem than obtaining their Hamming weight distributions. In fact, obtaining these distributions is a problem that usually involves the evaluation of sophisticated exponential sums, which leaves this problem open for most of the linear codes. In this work we present a method that uses the known complete weight distribution of a given cyclic code, to determine the complete weight distributions of other cyclic codes. In addition we also obtain the complete weight distributions for a particular kind of one- and two-weight irreducible cyclic codes, and use these distributions and the method, in order to determine the complete weight distributions of infinite families of cyclic codes. As an example, and as a particular instance of our results, we determine in a simple way the complete weight distribution for one of the two families of reducible cyclic codes studied by Bae, Li and Yue [Discrete Mathematics, 338 (2015) 2275-2287].
