近年来,由于其在秘密共享、认证码、关联方案和强正则图等方面的应用,具有少量权值的线性码得到了广泛的研究。本文构造了Fp上的几类少权线性码,其中p是奇素数。这些构造的码的重量分布也解决了有限域上的二次型和高斯和理论的应用。得到的一些线性码是最优或几乎最优的。这些线性码的参数在大多数情况下是新的。此外,还得到了两类MDS码。
Recently, linear codes with a few weights have been constructed and extensively studied due to their applications in secret sharing, authentication codes, association schemes, and strongly regular graphs. In this paper, we construct several classes of linear codes with a few weights over F p, where p is an odd prime. The weight distributions of these constructed codes are also settled by applications of the theory of quadratic forms and Gauss sums over finite fields. Some of the linear codes obtained are optimal or almost optimal. The parameters of these linear codes are new in most cases. Moreover, two classes of MDS codes are obtained.
