Delay-doppler-based key generation using OTFS
(Institute of Electrical and Electronics Engineers Inc., 2023)
Key generation for secure communication is challenging in high-mobility scenarios due to the low coherence time. This is further exacerbated in frequency-division duplex systems due to the non-reciprocal wireless channel ...
Sparsifying dictionary learning for beamspace channel representation and estimation in millimeter-wave massive MIMO
(Institute of Electrical and Electronics Engineers Inc., 2023)
Millimeter-wave (mmWave) massive multiple-input-multiple-output (mMIMO) is reported as a key enabler in fifth-generation communication and beyond. It is customary to use a lens antenna array to transform a mmWave mMIMO ...
PLS-IoT enhancement against eavesdropping via spatially distributed constellation obfuscation
(Institute of Electrical and Electronics Engineers Inc., 2023)
Wireless communication has become a ubiquitous facet of modern-day life. With the advent of Internet of Things (IoT) and massive machine-type connectivity, the number of devices is expected to increase even more. However, ...
Public safety network design for broadband wireless access
(Frontiers Media SA, 2023)

Quasisynchronous LoRa for LEO nanosatellite communications
(Institute of Electrical and Electronics Engineers Inc., 2023)
Perfect synchronization in LoRa communications between Low Earth Orbit (LEO) satellites and ground base stations is still challenging, despite the potential use of atomic clocks in LEO satellites, which offer high precision. ...
Network-independent and user-controlled RIS: An experimental perspective
(IEEE Computer Society, 2023)
The march towards 6G is accelerating and future wireless network architectures require enhanced performance along with significant coverage especially, to combat impairments on account of the wireless channel. Reconfigurable ...
Sequency index modulation: A novel index modulation for delay-sequency domain waveforms
(Institute of Electrical and Electronics Engineers Inc., 2023)
In this letter, the sequency domain is introduced as a novel resource to propose a new index modulation, which is named sequency index modulation (SeIM). In SeIM, information bits are implicitly conveyed through the indices ...
Exploiting OTFS frame structure for PAPR reduction
(Institute of Electrical and Electronics Engineers Inc., 2022)
Wireless technologies have always been the cornerstone of industrial progress. However, as industrial technologies have improved and advanced services have emerged, the demands of industry have meant that wireless technologies ...
Waveform design with constellation extension for OFDM dual-functional radar-communications
(Institute of Electrical and Electronics Engineers Inc., 2023)
Orthogonal frequency division multiplexing (OFDM) is widely used and works efficiently for the communication, but emerging applications requires OFDM to be flexible to meet sensing requirements. The time-frequency waveform ...
