Spatially Sparse Precoding in Wideband Hybrid Terahertz Massive MIMO Systems
Jiabao Gao, Caijun Zhong, Geoffrey Ye Li +2
In terahertz (THz) massive multiple-input multiple-output (MIMO) systems, the combination of huge bandwidth and massive antennas results in severe beam split, thus making the conve…
Learning Perturbations for Soft-Output Linear MIMO Demappers
Daniel E. Worrall, Markus Peschl, Arash Behboodi +1
Tree-based demappers for multiple-input multiple-output (MIMO) detection such as the sphere decoder can achieve near-optimal performance but incur high computational cost due to th…
Deep Learning-based Channel Estimation for Wideband Hybrid MmWave Massive MIMO
Jiabao Gao, Caijun Zhong, Geoffrey Ye Li +2
Hybrid analog-digital (HAD) architecture is widely adopted in practical millimeter wave (mmWave) massive multiple-input multiple-output (MIMO) systems to reduce hardware cost and e…
MIMO-GAN: Generative MIMO Channel Modeling
Tribhuvanesh Orekondy, Arash Behboodi, Joseph B. Soriaga
We propose generative channel modeling to learn statistical channel models from channel input-output measurements. Generative channel models can learn more complicated distribution…
Neural RF SLAM for unsupervised positioning and mapping with channel state information
Shreya Kadambi, Arash Behboodi, Joseph B. Soriaga +4
We present a neural network architecture for jointly learning user locations and environment mapping up to isometry, in an unsupervised way, from channel state information (CSI) va…
Sensing Matrix Design and Sparse Recovery on the Sphere and the Rotation Group
Arya Bangun, Arash Behboodi, Rudolf Mathar
In this paper, {the goal is to design deterministic sampling patterns on the sphere and the rotation group} and, thereby, construct sensing matrices for sparse recovery of band-lim…
The Restricted Isometry Property of Block Diagonal Matrices for Group-Sparse Signal Recovery
Niklas Koep, Arash Behboodi, Rudolf Mathar
Group-sparsity is a common low-complexity signal model with widespread application across various domains of science and engineering. The recovery of such signal ensembles from com…
A Mathematical Model for Fingerprinting-based Localization Algorithms
Arash Behboodi, Filip Lemic, Adam Wolisz
A general theoretical framework for Fingerprinting Localization Algorithms (FPS), given their popularity, can be utilized for their performance studies. In this work, after setting…
Sparse recovery in Wigner-D basis expansion
Arya Bangun, Arash Behboodi, Rudolf Mathar
We are concerned with the recovery of sparse Wigner-D expansions in terms of Wigner-D functions. Considered as a generalization of spherical harmonics, Wigner-D functions a…
Mixed Noisy Network Coding and Cooperative Unicasting in Wireless Networks
Arash Behboodi, Pablo Piantanida
The problem of communicating a single message to a destination in presence of multiple relay nodes, referred to as cooperative unicast network, is considered. First, we introduce "…
Selective Coding Strategy for Unicast Composite Networks
Arash Behboodi, Pablo Piantanida
Consider a composite unicast relay network where the channel statistic is randomly drawn from a set of conditional distributions indexed by a random variable, which is assumed to b…
Cooperative Strategies for Simultaneous and Broadcast Relay Channels
Arash Behboodi, Pablo Piantanida
Consider the \emph{simultaneous relay channel} (SRC) which consists of a set of relay channels where the source wishes to transmit common and private information to each of the des…
Broadcasting over the Relay Channel with Oblivious Cooperative Strategy
Arash Behboodi, Pablo Piantanida
This paper investigates the problem of information transmission over the simultaneous relay channel with two users (or two possible channel outcomes) where for one of them the more…
Capacity of a Class of Broadcast Relay Channels
Arash Behboodi, Pablo Piantanida
Consider the broadcast relay channel (BRC) which consists of a source sending information over a two user broadcast channel in presence of two relay nodes that help the transmissio…
