Ring geometries, two-weight codes, and strongly regular graphs
It is known that a linear two-weight code C over a finite field Fq corresponds both to a multiset in a projective space over Fq that meets every hyperplane in either a or b points for some integers a < b , and to a strongly regular graph whose vertices may be identified with the codewords of C . Here we extend this classical result to the case of a ring-linear code with exactly two nonzero homo...
متن کاملSome ternary cubic two-weight codes
We study trace codes with defining set L, a subgroup of the multiplicative group of an extension of degree m of the alphabet ring F3+uF3+u 2 F3, with u 3 = 1. These codes are abelian, and their ternary images are quasi-cyclic of co-index three (a.k.a. cubic codes). Their Lee weight distributions are computed by using Gauss sums. These codes have three nonzero weights when m is singly-even and |...
متن کاملTwo-weight codes, graphs and orthogonal arrays
We investigate properties of two-weight codes over finite Frobenius rings, giving constructions for the modular case. A δ-modular code [15] is characterized as having a generator matrix where each column g appears with multiplicity δ|gR×| for some δ ∈ Q. Generalizing [10] and [5], we show that the additive group of a two-weight code satisfying certain constraint equations (and in particular a m...
متن کاملDirected Strongly Regular Graphs and Their Codes
Directed Strongly Regular Graphs (DSRG) were introduced by Duval as a generalization of strongly regular graphs (SRG’s) [4]. As observed in [8] a special case of these are the doubly regular tournaments or equivalently, the skew Hadamard matrices. As the latter already lead to many interesting codes [10] it is natural to consider the more general case of codes constructed from the adjacency mat...
متن کاملTwo classes of ternary codes and their weight distributions
In this paper we describe two classes of ternary codes, determine their minimum weight and weight distribution, and prove their properties. We also present four classes of 1-designs that are based on the classes of ternary codes.
