DOI: 10.1109/lwc.2022.3192795
Abstract: In this letter, we propose faster-than-Nyquist (FTN) signaling transmission that is robust for an underwater acoustic (UWA) doubly selective channel. Owning to the explicit benefits of a reduced symbol interval specific to FTN signaling, the… read more here.

DOI: 10.1109/tcomm.2022.3171815
Abstract: Sparse Bayesian learning (SBL)-based channel state information (CSI) estimation schemes are developed for filter bank multicarrier (FBMC) systems using offset quadrature amplitude modulation (OQAM). Initially, an SBL-based channel estimation scheme is designed for a frequency-selective… read more here.

DOI: 10.1109/tvt.2019.2918565
Abstract: Spectrum sensing for fast-moving vehicles in cognitive radios over a general line-of-sight (LOS) doubly selective fading channel, which is a practical environment for modern mobile orthogonal frequency-division multiplexing communications, should be addressed. However, time- and… read more here.

DOI: 10.1109/tvt.2021.3089167
Abstract: This paper proposes affine-precoded superimposed pilot (SIP) design, followed by channel state information (CSI) estimation techniques for millimeter wave (mmWave) MIMO-OFDM systems. Toward this end, a multiple measurement vector (MMV) sparse Bayesian learning (SBL)-based SIP… read more here.
