WebUsing this, we show that, for each linear code C and any integer r ≤ k = dim C, a linear code exists whose weight distribution corresponds to a part of the generalized weight spectrum of C, from the r th weights to the k th. In particular, the minimum distance of this code is proportional to the r th generalized weight of C. WebMotivated by cryptographical applications, the algebraic structure, of linear codes from a new perspective is studied. By viewing the minimum Hamming weight as a certain minimum property of one-dimensional subcodes, a generalized notion of higher-dimensional Hamming weights is obtained. These weights characterize the code … Web摘要: Motivated by cryptographical applications, the algebraic structure, of linear codes … quick cooking long grain brown rice
