Bounds on subspace codes based on subspaces of type (s,0,0,0) in pseudo-sympletic spaces and singular pseudo-symplectic spaces

摘要

In this article, we compute the Sphere-packing bound, Singleton bound, Gilbert-Varshamov bound and Wang-Xing-Safavi-Naini (W-X-S-N) bound on the subspace codes (2n+σ,H,ρ,(s,0,0,0))q on the premise of subspaces with the form of (s,0,0,0) in pseudo-sympletic spaces Fq2n+σ and on the subspace codes (2n+σ+μ,H,ρ,(s,0,0,0))q on the premise of subspaces with the form of (s,0,0,0) in singular pseudo-sympletic spaces Fq(2n+σ+μ).
