Witrynalength n is called Hermitian self-dual if C = C⊥H, where C⊥H denotes the Hermitian dual code of C which is defined as C⊥H:= {v ∈Fn q u·v = 0 for all u ∈C}. Most of the results in this paper are stated for Fq-linear codes with usual inner product but it can be re-phrased with equal validity to the case of the codes with the ... WitrynaThe Hermitian inner product of elements is defined as , for and . For a linear code of length over , the Hermitian dual code of is defined by . If , then is known as Hermitian self-dual and is Hermitian self-orthogonal if . Aydin et al. dealt with constacyclic codes and a constacyclic BCH bound was given.
WitrynaThe dimension of such Hermitian dual-containing negacyclic codes is completely determined by analyzing cyclotomic cosets. Quantum negacyclic BCH codes of length n = q 2 m − 1 2 are obtained by using Hermitian construction. The constructed quantum negacyclic BCH codes produce new quantum codes with parameters better than … Witryna5 paź 2024 · A Hermitian matrix can be diagonalized if and only if it has no right subeigenvalues. Then we present the singular value decomposition for general dual complex matrices. The results are further extended to dual quaternion matrices.
