Lossless Size Reduction for Integer Least Squares with Application to Sphere Decoding
Mohammad Neinavaie, Mostafa Derakhtian, Sergiy A. Vorobyov
Minimum achievable complexity (MAC) for a maximum likelihood (ML) performance-achieving detection algorithm is derived. Using the derived MAC, we prove that the conventional sphere…
A Complexity Efficient DMT-Optimal Tree Pruning Based Sphere Decoding
Mohammad Neinavaie, Mostafa Derakhtian, Negar Daryanavardan +1
We present a diversity multiplexing tradeoff (DMT) optimal tree pruning sphere decoding algorithm which visits merely a single branch of the search tree of the sphere decoding (SD)…
Quadratic Matrix Inequality Approach to Robust Adaptive Beamforming for General-Rank Signal Model
Yongwei Huang, Sergiy A. Vorobyov, Zhi-Quan Luo
The worst-case robust adaptive beamforming problem for general-rank signal model is considered. This is a nonconvex problem, and an approximate version of it (obtained by introduci…
Toward Millimeter Wave Joint Radar-Communications: A Signal Processing Perspective
Kumar Vijay Mishra, Bhavani Shankar M. R., Visa Koivunen +2
Synergistic design of communications and radar systems with common spectral and hardware resources is heralding a new era of efficiently utilizing a limited radio-frequency spectru…
A Fast Dictionary Learning Method for Coupled Feature Space Learning
F. G. Veshki, S. A. Vorobyov
In this letter, we propose a novel computationally efficient coupled dictionary learning method that enforces pairwise correlation between the atoms of dictionaries learned to repr…
Adaptive Virtual Waveform Design for Millimeter-Wave Joint Communication-Radar
Preeti Kumari, Sergiy A. Vorobyov, Robert W. Heath
Joint communication and radar (JCR) waveforms with fully digital baseband generation and processing can now be realized at the millimeter-wave (mmWave) band. Prior work has propose…
