Robust 2-D DOA Estimation in a Polarization Sensitive Single User Environment

no code implementations14 Mar 2022 Md Imrul Hasan, Mohammad Saquib

A low complexity algorithm that estimates the DOA angles in a closed-form manner is developed.

Low Complexity Single Source DOA Estimation Based on Reduced Dimension SVR

no code implementations19 Oct 2021 Md Imrul Hasan, Mohammad Saquib

Conventional direction of arrival (DOA) estimation algorithms suffer from performance degradation due to antenna pattern distortion and substantial computational complexity in real-time execution.


Rectangular Planar vs Concentric Circular Array for 5G Beamforming

no code implementations2 Aug 2021 Md Imrul Hasan, Mohammad Saquib

The transmitter signals in the fifth generation (5G) wireless networks suffer from significant path loss due to the use of higher frequencies in Sub-6 GHz and millimeter-wave (mmWave) bands.

CovTANet: A Hybrid Tri-level Attention Based Network for Lesion Segmentation, Diagnosis, and Severity Prediction of COVID-19 Chest CT Scans

no code implementations3 Jan 2021 Tanvir Mahmud, Md. Jahin Alam, Sakib Chowdhury, Shams Nafisa Ali, Md Maisoon Rahman, Shaikh Anowarul Fattah, Mohammad Saquib

A multi-phase optimization strategy is introduced for solving the challenges of complicated diagnosis at a very early stage of infection, where an efficient lesion segmentation network is optimized initially which is later integrated into a joint optimization framework for the diagnosis and severity prediction tasks providing feature enhancement of the infected regions.

Co-Designing Statistical MIMO Radar and In-band Full-Duplex Multi-User MIMO Communications

no code implementations26 Jun 2020 Jiawei Liu, Kumar Vijay Mishra, Mohammad Saquib

We consider a spectral sharing problem in which a statistical (or widely distributed) multiple-input-multiple-output (MIMO) radar and an in-band full-duplex (IBFD) multi-user MIMO (MU-MIMO) communications system concurrently operate within the same frequency band.
