On Multiplicative Matrix Channels over Finite Chain Rings
Roberto W. Nóbrega, Chen Feng, Danilo Silva +1
Motivated by physical-layer network coding, this paper considers communication in multiplicative matrix channels over finite chain rings. Such channels are defined by the law $Y =A…
Communication over Finite-Chain-Ring Matrix Channels
Chen Feng, Roberto W. Nóbrega, Frank R. Kschischang +1
Though network coding is traditionally performed over finite fields, recent work on nested-lattice-based network coding suggests that, by allowing network coding over certain finit…
On the Capacity of Multiplicative Finite-Field Matrix Channels
Roberto W. Nóbrega, Danilo Silva, Bartolomeu F. Uchôa-Filho
This paper deals with the multiplicative finite-field matrix channel, a discrete memoryless channel whose input and output are matrices (over a finite field) related by a multiplic…
The Capacity of Random Linear Coding Networks as Subspace Channels
Bartolomeu F. Uchoa-Filho, Roberto W. Nobrega
In this paper, we consider noncoherent random linear coding networks (RLCNs) as a discrete memoryless channel (DMC) whose input and output alphabets consist of subspaces. This cont…
Multishot Codes for Network Coding using Rank-Metric Codes
Roberto W. Nobrega, Bartolomeu F. Uchoa-Filho
The multiplicative-additive finite-field matrix channel arises as an adequate model for linear network coding systems when links are subject to errors and erasures, and both the ne…
Multishot Codes for Network Coding: Bounds and a Multilevel Construction
Roberto W. Nobrega, Bartolomeu F. Uchoa-Filho
The subspace channel was introduced by Koetter and Kschischang as an adequate model for the communication channel from the source node to a sink node of a multicast network that pe…
