Real-Time Radio Technology and Modulation Classification via an LSTM Auto-Encoder
Ziqi Ke, Haris Vikalo
Identification of the type of communication technology and/or modulation scheme based on detected radio signal are challenging problems encountered in a variety of applications inc…
Submodular Observation Selection and Information Gathering for Quadratic Models
Abolfazl Hashemi, Mahsa Ghasemi, Haris Vikalo +1
We study the problem of selecting most informative subset of a large observation set to enable accurate estimation of unknown parameters. This problem arises in a variety of settin…
Randomized Greedy Sensor Selection: Leveraging Weak Submodularity
Abolfazl Hashemi, Mahsa Ghasemi, Haris Vikalo +1
We study the problem of estimating a random process from the observations collected by a network of sensors that operate under resource constraints. When the dynamics of the proces…
Near-Optimal Distributed Estimation for a Network of Sensing Units Operating Under Communication Constraints
Abolfazl Hashemi, Osman Fatih Kilic, Haris Vikalo
We study the problem of distributed state estimation in a network of sensing units that can exchange their measurements but the rate of communication between the units is constrain…
A Novel Scheme for Support Identification and Iterative Sampling of Bandlimited Graph Signals
Abolfazl Hashemi, Rasoul Shafipour, Haris Vikalo +1
We study the problem of sampling and reconstruction of bandlimited graph signals where the objective is to select a node subset of prescribed cardinality that ensures interpolation…
Towards Accelerated Greedy Sampling and Reconstruction of Bandlimited Graph Signals
Abolfazl Hashemi, Rasoul Shafipour, Haris Vikalo +1
We study the problem of sampling and reconstructing spectrally sparse graph signals where the objective is to select a subset of nodes of prespecified cardinality that ensures inte…
