OTFS-FMCW waveform design for low complexity joint sensing and communication
(Institute of Electrical and Electronics Engineers Inc., 2022)
Joint sensing and communication (JSAC) systems are becoming attractive technologies since they can map the radio environment while performing communication using the same frequency bands. This is achieved by radar signal ...
A novel method for joint sensing and communication at terahertz frequencies by exploiting rough surfaces
(Institute of Electrical and Electronics Engineers Inc., 2022)
In this paper, a novel method for joint sensing and communication (JSAC) is proposed by exploiting the scattering properties of a rough surface present in the environment in the terahertz (THz) frequency range. At higher ...
Beam squint inspired multiple access technique in massive MIMO systems
(Institute of Electrical and Electronics Engineers Inc., 2022)
Massive multiple-input multiple-output (mMIMO) systems implementing wideband signaling have been found to suffer from beam squinting problem. In multicarrier systems, beam squint causes spreading of the beam to multiple ...
