Probability-based pilot allocation for MIMO relay Distributed compressed sensing channel estimation [PDF]

open access: goldEURASIP Journal on Advances in Signal Processing, 2018
Multiple-Input Multiple-Output (MIMO) relay communication systems are used as an efficient system in spectral efficiency and power allocation view point. In these systems, some of the facilities need channel state information (CSI).

Communication-Efficient Distributed SGD With Compressed Sensing [PDF]

open access: yesIEEE Control Systems Letters, 2022
We consider large scale distributed optimization over a set of edge devices connected to a central server, where the limited communication bandwidth between the server and edge devices imposes a significant bottleneck for the optimization procedure. Inspired by recent advances in federated learning, we propose a distributed stochastic gradient descent (

Distributed Compressed Video Sensing [PDF]

open access: yes2009 43rd Annual Conference on Information Sciences and Systems, 2009
This paper proposes a novel framework called Distributed Compressed Video Sensing (DISCOS) - a solution for Distributed Video Coding (DVC) based on the Compressed Sensing (CS) theory. The DISCOS framework compressively samples each video frame independently at the encoder and recovers video frames jointly at the decoder by exploiting an interframe ...

Distributed quantization for compressed sensing [PDF]

open access: yes2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2014
We study distributed coding of compressed sensing (CS) measurements using vector quantizer (VQ). We develop a distributed framework for realizing optimized quantizer that enables encoding CS measurements of correlated sparse sources followed by joint decoding at a fusion center.
