Two-way Communication with Adaptive Data Acquisition
Behzad Ahmadi, Osvaldo Simeone
Motivated by computer networks and machine-to-machine communication applications, a bidirectional link is studied in which two nodes, Node 1 and Node 2, communicate to fulfill gene…
Information Embedding on Actions
Behzad Ahmadi, Himanshu Asnani, Osvaldo Simeone +1
The problem of optimal actuation for channel and source coding was recently formulated and solved in a number of relevant scenarios. In this class of models, actions are taken at e…
Cascade Source Coding with a Side Information "Vending Machine"
Behzad Ahmadi, Chiranjib Choudhuri, Osvaldo Simeone +1
The model of a side information "vending machine" (VM) accounts for scenarios in which the measurement of side information sequences can be controlled via the selection of cost-con…
On Channels with Action-Dependent States
Behzad Ahmadi, Osvaldo Simeone
Action-dependent channels model scenarios in which transmission takes place in two successive phases. In the first phase, the encoder selects an "action" sequence, with the twofold…
Heegard-Berger and Cascade Source Coding Problems with Common Reconstruction Constraints
Behzad Ahmadi, Ravi Tandon, Osvaldo Simeone +1
For the HB problem with the CR constraint, the rate-distortion function is derived under the assumption that the side information sequences are (stochastically) degraded. The rate-…
Distributed and Cascade Lossy Source Coding with a Side Information "Vending Machine"
Behzad Ahmadi, Osvaldo Simeone
Source coding with a side information "vending machine" is a recently proposed framework in which the statistical relationship between the side information and the source, instead…
