NettetBinary linear codes, two-to-one functions , 3-weight linear codes, constant-weight linear codes 1. INTRODUCTION Let qbe a power of a prime p,F qbe the ﬁnite ﬁeld of qelements and F∗ be its multiplicative group. An [n,k,d] linear code C over F qis a k-dimensional subspace of Fnwith minimum (Hamming) distance d. An Nettet1 The first-order binary Reed-Muller code is a [ 16, 5, 8] code and if we shorten this code by deleting the over-all parity check bit and taking only the remaining codewords of even weight, then we are left with a [ 15, 4, 8] linear binary code. Can this be shortened further to a [ 13, 4, 6] linear code? – Dilip Sarwate Nov 7, 2012 at 4:47 1 sowee smart charge

NettetIn linear algebra terms, the dual code is the annihilator of C with respect to the bilinear form . The dimension of C and its dual always add up to the length n : A generator matrix for the dual code is the parity-check matrix for the original code and vice versa. The dual of the dual code is always the original code.
