Graph Signal Processing Meets Blind Source Separation
Jari Miettinen, Eyal Nitzan, Sergiy A. Vorobyov +1
In graph signal processing (GSP), prior information on the dependencies in the signal is collected in a graph which is then used when processing or analyzing the signal. Blind sour…
Embedding a Heavy-Ball type of Momentum into the Estimating Sequences
Endrit Dosti, Sergiy A. Vorobyov, Themistoklis Charalambous
We present a new accelerated gradient-based method for solving smooth unconstrained optimization problems. The goal is to embed a heavy-ball type of momentum into the Fast Gradient…
Joint DOD and DOA Estimation in Slow-Time MIMO Radar via PARAFAC Decomposition
Feng Xu, Sergiy A. Vorobyov, Xiaopeng Yang
We develop a new tensor model for slow-time multiple-input multiple output (MIMO) radar and apply it for joint direction-of-departure (DOD) and direction-of-arrival (DOA) estimatio…
