A New Class of Composite Objective Multi-step Estimating-sequence Techniques (COMET)
Endrit Dosti, Sergiy A. Vorobyov, Themistoklis Charalambous
We devise a new accelerated gradient-based estimating sequence technique for solving large-scale optimization problems with composite structure. More specifically, we introduce a n…
Robust Adaptive Beamforming Maximizing the Worst-Case SINR over Distributional Uncertainty Sets for Random INC Matrix and Signal Steering Vector
Yongwei Huang, Wenzheng Yang, Sergiy A. Vorobyov
The robust adaptive beamforming (RAB) problem is considered via the worst-case signal-to-interference-plus-noise ratio (SINR) maximization over distributional uncertainty sets for…
DOA Estimation in Nonuniform Sensor Noise
Majdoddin Esfandiari, Sergiy A. Vorobyov
The problem of direction-of-arrival (DOA) estimation in the presence of nonuniform sensor noise is considered and a novel algorithm is developed. The algorithm consists of three ph…
Efficient ADMM-based Algorithms for Convolutional Sparse Coding
Farshad G. Veshki, Sergiy A. Vorobyov
Convolutional sparse coding improves on the standard sparse approximation by incorporating a global shift-invariant model. The most efficient convolutional sparse coding methods ar…
Two-Dimensional DOA Estimation for L-shaped Nested Array via Tensor Modeling
Feng Xu, Sergiy A. Vorobyov
The problem of two-dimensional (2-D) direction-of-arrival (DOA) estimation for the L-shaped nested array is considered. Typically, the multi-dimensional structure of the received s…
Transmit Beamspace DDMA Based Automotive MIMO Radar
Feng Xu, Sergiy A. Vorobyov, Fawei Yang
The time division multiple access (TDMA) technique has been applied in automotive multiple-input multiple-output (MIMO) radar. However, it suffers from the transmit energy loss, an…
