Design of Binary Quantizers for Distributed Detection under Secrecy Constraints
V. Sriram Siddhardh Nadendla, Pramod K. Varshney
In this paper, we investigate the design of distributed detection networks in the presence of an eavesdropper (Eve). We consider the problem of designing binary quantizers at the s…
Permutation Trellis Coded Multi-level FSK Signaling to Mitigate Primary User Interference in Cognitive Radio Networks
Raghed El-Bardan, Engin Masazade, Onur Ozdemir +2
We employ Permutation Trellis Code (PTC) based multi-level Frequency Shift Keying signaling to mitigate the impact of Primary Users (PUs) on the performance of Secondary Users (SUs…
On Quantizer Design for Distributed Bayesian Estimation in Sensor Networks
Aditya Vempaty, Hao He, Biao Chen +1
We consider the problem of distributed estimation under the Bayesian criterion and explore the design of optimal quantizers in such a system. We show that, for a conditionally unbi…
Distributed Inference in Tree Networks using Coding Theory
Bhavya Kailkhura, Aditya Vempaty, Pramod K. Varshney
In this paper, we consider the problem of distributed inference in tree based networks. In the framework considered in this paper, distributed nodes make a 1-bit local decision reg…
Decentralized and Collaborative Subspace Pursuit: A Communication-Efficient Algorithm for Joint Sparsity Pattern Recovery with Sensor Networks
Gang Li, Thakshila Wimalajeewa, Pramod K. Varshney
In this paper, we consider the problem of joint sparsity pattern recovery in a distributed sensor network. The sparse multiple measurement vector signals (MMVs) observed by all the…
Decentralized Subspace Pursuit for Joint Sparsity Pattern Recovery
Gang Li, Thakshila Wimalajeewa, Pramod K. Varshney
To solve the problem of joint sparsity pattern recovery in a decen-tralized network, we propose an algorithm named decentralized and collaborative subspace pursuit (DCSP). The basi…
