an algebraic construction for constant dimension subspace codes is called orbit code. it arises as the orbits under the action of a subgroup of the general linear group on subspaces in an ambient space. in particular orbit codes of a singer subgroup of the general linear group has investigated recently. in this paper, we consider the normalizer of a singer subgroup of the general linear group a...

Increasing network capacity is undoubtedly a critical aspect of modern communication systems. In this paper, the concept sub-rate coding and decoding in framework linear (LNC) introduced for single-source multiple-sinks finite acyclic networks. This methodology offers modification to existing LNC so that source transmits its messages manner which given set sinks (termed sinks), whose max-flow s...

Consider a communication network in which certain source nodes multicast information to other nodes on the network in the multihop fashion where every node can pass on any of its received data to others. We are interested in how fast each node can receive the complete information, or equivalently, what the information rate arriving at each node is. Allowing a node to encode its received data be...
