On a Class of Constant Weight Codes
For any odd prime power q we first construct a certain non-linear binary code C(q, 2) having (q − q)/2 codewords of length q and weight (q − 1)/2 each, for which the Hamming distance between any two distinct codewords is in the range [q/2 − 3√q/2, q/2 + 3√q/2] that is, ‘almost constant’. Moreover, we prove that C(q, 2) is distance-invariant. Several variations and improvements on this theme are...
متن کاملIsotropic Constant Dimension Subspace Codes
In network code setting, a constant dimension code is a set of k-dimensional subspaces of F nq . If F_q n is a nondegenerated symlectic vector space with bilinear form f, an isotropic subspace U of F n q is a subspace that for all x, y ∈ U, f(x, y) = 0. We introduce isotropic subspace codes simply as a set of isotropic subspaces and show how the isotropic property use in decoding process, then...

متن کاملQuantum codes over a class of finite chain ring
In this study, we introduce a new Gray map which preserves the orthogonality from the chain ring F2 [u] / (u) to F s 2 where F2 is the finite field with two elements. We also give a condition of the existence for cyclic codes of odd length containing its dual over the ring F2 [u] / (u) . By taking advantage of this Gray map and the structure of the ring, we obtain two classes of binary quantum ...
متن کاملA class of one-dimensional MDS convolutional codes
A class of one-dimensional convolutional codes will be presented. They are all MDS codes, i. e., have the largest distance among all one-dimensional codes of the same length n and overall constraint length δ. Furthermore, their extended row distances are computed, and they increase with slope n − δ. In certain cases of the algebraic parameters, we will also derive parity check matrices of Vande...
