Dense packings from quadratic fields and codes


In the present paper, we make use of the quadratic field Q( √−3 ) to construct dense packings in the Euclidean spaces. With the help from good error-correcting codes, we are able to produce several packings with the best-known densities. Furthermore, if we assume that the best upper bound in coding theory developed by Aaltonen, Ben-Haim and Litsyn could be… (More)
