Toward one Symbol Network Coding Vectors

Pascal Frossard, Nikolaos Thomos

In this paper, we propose a novel design for network coding vectors that limits the overhead information. Network coding vectors contain information regarding the operations the packets have undergone in the network nodes. They are used at the decoder side ...

Coding in the Presence of Semantic Value of Information: Unequal Error Protection Using Poset Decoders

In this work we explore possibilities for coding when information worlds have different (semantic) values. We introduce a loss function that expresses the overall performance of a coding scheme for discrete channels and exchange the usual goal of minimizin ...

Continuous-Domain ARMA Modeling for Ultrasound Tissue Characterization

Michaël Unser, Simona Maggio

In this study, we investigate the possibility of applying a continuous-time ARMA (CARMA) model to radio-frequency ultrasound signals. We consider the effect of the discretization process on the parameters of the continuous system, and we take into account ...
