Several classes of projective few-weight linear codes and their applications
It is well-known that few-weight linear codes have better applications in
secret sharing schemes \cite{JY2006,CC2005}.In particular, projective
two-weight codes are very precious as they are closely related to finite
projective spaces, strongly regular graphs and combinatorial designs
\cite{RC1986,CD2018,P1972}. Here, we present the following two applications.Comment: arXiv admin note: text overlap with arXiv:2107.0244
Two classes of two-weight linear codes over finite fields
Let be a prime, a positive integer, the multiplicative order of modulo , and let , where is the Euler's function. In this paper, we construct two classes of linear codes over and investigate their weight distributions. By calculating two classes of special exponential sums, the desired results are obtained
