Optimal detection and error exponents for hidden multi-state processes via random duration model approach
Dragana Bajović, Kanghang He, Lina Stanković +2
We study detection of random signals corrupted by noise that over time switch their values (states) from a finite set of possible values, where the switchings occur at unknown poin…
Linear State Estimation via 5G C-RAN Cellular Networks using Gaussian Belief Propagation
Mirsad Cosovic, Dejan Vukobratovic, Vladimir Stankovic
Machine-type communications and large-scale information processing architectures are among key (r)evolutionary enhancements of emerging fifth-generation (5G) mobile cellular networ…
Detecting random walks on graphs with heterogeneous sensors
Dragana Bajovic, José M. F. Moura, Dejan Vukobratovic
We consider the problem of detecting a random walk on a graph, based on observations of the graph nodes. When visited by the walk, each node of the graph observes a signal of eleva…
User Activity Detection in Massive Random Access: Compressed Sensing vs. Coded Slotted ALOHA
Veljko Boljanovic, Dejan Vukobratovic, Petar Popovski +1
Machine-type communication services in mobile cel- lular systems are currently evolving with an aim to efficiently address a massive-scale user access to the system. One of the key…
Cooperative Slotted ALOHA for Massive M2M Random Access Using Directional Antennas
Aleksandar Mastilovic, Dejan Vukobratovic, Dusan Jakovetic +1
Slotted ALOHA (SA) algorithms with Successive Interference Cancellation (SIC) decoding have received significant attention lately due to their ability to dramatically increase the…
Fast Real-Time DC State Estimation in Electric Power Systems Using Belief Propagation
Mirsad Cosovic, Dejan Vukobratovic
We propose a fast real-time state estimator based on the belief propagation algorithm for the power system state estimation. The proposed estimator is easy to distribute and parall…
