Low Complexity Channel Estimation for Millimeter Wave Systems with Hybrid A/D Antenna Processing
George C. Alexandropoulos, Symeon Chouvardas
The availability of large bandwidth at millimeter wave (mmWave) frequencies is one of the major factors that rendered very high frequencies a promising candidate enabler for fifth…
Robust On-line Matrix Completion on Graphs
Symeon Chouvardas, Mohammed Amin Abdullah, Lucas Claude +1
We study online robust matrix completion on graphs. At each iteration a vector with some entries missing is revealed and our goal is to reconstruct it by identifying the underlying…
A Diffusion Kernel LMS algorithm for nonlinear adaptive networks
Symeon Chouvardas, Moez Draief
This work presents a distributed algorithm for nonlinear adaptive learning. In particular, a set of nodes obtain measurements, sequentially one per time step, which are related via…
