Downlink Transmission in FBMC-based Massive MIMO with Co-located and Distributed Antennas
(2024)This paper introduces a practical precoding method for the downlink of Filter Bank Multicarrier-based (FBMC-based) massive multiple-input multiple-output (MIMO) systems. The proposed method comprises a two-stage precoder, ... -
Joint Channel Estimation and Equalization in Massive MIMO Using a Single Pilot Subcarrier
(2023)The focus of this letter is on the reduction of the large pilot overhead in orthogonal frequency division multi-plexing (OFDM) based massive multiple-input multiple-output (MIMO) systems. We propose a novel joint channel ... -
Low-Complexity Equalization and Detection for OTFS-NOMA
(2023)Orthogonal time frequency space (OTFS) modula- tion has recently emerged as a potential 6G candidate waveform which provides improved performance in high-mobility scenarios. In this paper we investigate the combination ... -
Low-Complexity Reliability-Based Equalization and Detection for OTFS-NOMA
(2023)Orthogonal time frequency space (OTFS) modula- tion has recently emerged as a potential 6G candidate waveform which provides improved performance in high-mobility scenarios. In this paper we investigate the combination ... -
A Practical Pilot for Channel Estimation of OTFS
(2023)The widely used embedded impulse pilot for channel estimation of orthogonal time frequency space modulation (OTFS) has a prohibitively large peak to average power ratio (PAPR). Hence, in this paper, we propose a novel ... -
Practical Synchronization for OTFS
(2023)In the existing literature on joint timing and frequency synchronization of orthogonal time frequency space modulation (OTFS), practically infeasible impulse pilot with large peak-to-average power ratio (PAPR) is deployed. ... -
RIS Meets Aerodynamic HAPS: A Multi-Objective Optimization Approach
(2023)In this letter, we propose a novel network architecture for integrating terrestrial and non-terrestrial networks (NTNs) to establish connection between terrestrial ground stations which are unconnected due to blockage. ... -
Small Dual-Band 3D Beamforming MIMO Antenna
(IEEE, 2023)This work proposes a small dual-band (2.4 GHz and 4.89 GHz bands) 3D beamforming Multiple-Input Multiple-Output (MIMO) antenna for emerging size-constrained Internet of Things (IoT) applications. The performance is realized ... -
Time and Frequency Synchronization for OTFS
(2022)In this letter, we propose timing offset (TO) and carrier frequency offset (CFO) estimators for orthogonal time frequency space modulation (OTFS). The proposed estimators do not require any additional training overheads ... -
Transcutaneous spinal cord stimulation and motor responses in individuals with spinal cord injury: A methodological review
(2021)Background Transcutaneous spinal cord stimulation (tSCS) is a non-invasive modality in which electrodes can stimulate spinal circuitries and facilitate a motor response. This review aimed to evaluate the methodology of ...
