Linear Codes With Two or Three Weights From Some Functions With Low Walsh Spectrum in Odd Characteristic

Linear codes with few weights have applications in authentication codes, secrete sharing schemes, association schemes, consumer electronics and data storage system. In this paper, several classes of linear codes with two or three weights are obtained from some functions with low Walsh spectrum in odd characteristic. Numerical results show that some of the linear codes obtained are optimal or almost optimal in the sense that they meet certain bounds on linear codes.
