LSST: Learned Single-Shot Trajectory and Reconstruction Network for MR Imaging
Hemant Kumar Aggarwal, Sudhanya Chatterjee, Dattesh Shanbhag +2
Single-shot magnetic resonance (MR) imaging acquires the entire k-space data in a single shot and it has various applications in whole-body imaging. However, the long acquisition t…
Unfolding for Joint Channel Estimation and Symbol Detection in MIMO Communication Systems
Swati Bhattacharya, K. V. S. Hari, Yonina C. Eldar
This paper proposes a Joint Channel Estimation and Symbol Detection (JED) scheme for Multiple-Input Multiple-Output (MIMO) wireless communication systems. Our proposed method for J…
Learning a Common Dictionary for CSI Feedback in FDD Massive MU-MIMO-OFDM Systems
Pavan Kumar Gadamsetty, K. V. S. Hari, Lajos Hanzo
In a transmit preprocessing aided frequency division duplex (FDD) massive multi-user (MU) multiple-input multiple-output (MIMO) scheme assisted orthogonal frequency-division multip…
A Risk Minimization Framework for Channel Estimation in OFDM Systems
Karthik Upadhya, Chandra Sekhar Seelamantula, K. V. S. Hari
We address the problem of channel estimation for cyclic-prefix (CP) Orthogonal Frequency Division Multiplexing (OFDM) systems. We model the channel as a vector of unknown determini…
A Fast Eigen Solution for Homogeneous Quadratic Minimization with at most Three Constraints
Dinesh Dileep Gaurav, K. V. S. Hari
We propose an eigenvalue based technique to solve the Homogeneous Quadratic Constrained Quadratic Programming problem (HQCQP) with at most 3 constraints which arise in many signal…
Low Complexity Joint Estimation of Synchronization Impairments in Sparse Channel for MIMO-OFDM System
Renu Jose, Sooraj K. Ambat, K. V. S. Hari
Low complexity joint estimation of synchronization impairments and channel in a single-user MIMO-OFDM system is presented in this letter. Based on a system model that takes into ac…
