Primary User Localization and Online Radio Cartography via Structured Tensor Decomposition
Mohsen Joneidi, Nazanin Rahnavard
Source localization and radio cartography using multi-way representation of spectrum is the subject of study in this paper. A joint matrix factorization and tensor decomposition pr…
Feedback Acquisition and Reconstruction of Spectrum-Sparse Signals by Predictive Level Comparisons
Mahdi Boloursaz Mashhadi, Saeed Gazor, Nazanin Rahnavard +1
In this letter, we propose a sparsity promoting feedback acquisition and reconstruction scheme for sensing, encoding and subsequent reconstruction of spectrally sparse signals. In…
Distributed Binary Detection over Fading Channels: Cooperative and Parallel Architectures
Nahal Maleki, Azadeh Vosoughi, Nazanin Rahnavard
This paper considers the problem of binary distributed detection of a known signal in correlated Gaussian sensing noise in a wireless sensor network, where the sensors are restrict…
Matrix Coherency Graph: A Tool for Improving Sparse Coding Performance
Mohsen Joneidi, Mahdi Barzegar Khalilsarai, Alireza Zaeemzadeh +1
Exact recovery of a sparse solution for an underdetermined system of linear equations implies full search among all possible subsets of the dictionary, which is computationally int…
Union of Low-Rank Subspaces Detector
Mohsen Joneidi, Parvin Ahmadi, Mostafa Sadeghi +1
The problem of signal detection using a flexible and general model is considered. Due to applicability and flexibility of sparse signal representation and approximation, it has att…
Distributed Rateless Codes with UEP Property
Ali Talari, Nazanin Rahnavard
When multiple sources of data need to transmit their rateless coded symbols through a single relay to a common destination, a distributed rateless code instead of several separate…
Efficient Symbol Sorting for High Intermediate Recovery Rate of LT Codes
Ali Talari, Behzad Shahrasbi, Nazanin Rahnavard
LT codes are modern and efficient rateless forward error correction (FEC) codes with close to channel capacity performance. Nevertheless, in intermediate range where the number of…
