RIS-Enabled Passive Radar towards Target Localization
Ahmad Bazzi, Marwa Chafii
In this paper, we study a communication-centric integrated sensing and communication (ISAC) approach, where an access point (AP) communicates with users, while a passive radar (PR)…
Dual-Mode Time Domain Multiplexed Chirp Spread Spectrum
Ali Waqar Azim, Ahmad Bazzi, Mahrukh Fatima +2
We propose a dual-mode (DM) time domain multiplexed (TDM) chirp spread spectrum (CSS) modulation for spectral and energy-efficient low-power wide-area networks (LPWANs). DM-CSS mod…
On Integrated Sensing and Communication Waveforms with Tunable PAPR
Ahmad Bazzi, Marwa Chafii
We present a novel approach to the problem of dual-functional radar and communication (DFRC) waveform design with adjustable peak-to-average power ratio (PAPR), while minimizing th…
Chirp Spread Spectrum-based Waveform Design and Detection Mechanisms for LPWAN-based IoT -- A Survey
Ali Waqar Azim, Ahmad Bazzi, Raed Shubair +1
LoRa is a widely adopted method of utilizing chirp spread spectrum (CSS) techniques at the physical (PHY) layer to facilitate low-power wide-area network (LPWAN) connectivity. By t…
On Outage-based Beamforming Design for Dual-Functional Radar-Communication 6G Systems
Ahmad Bazzi, Marwa Chafii
This article studies and derives beamforming design in a dual-functional radar-communication (DFRC) multiple-input-multiple-output system. We focus on a scenario, where the DFRC ba…
Dual-Mode Chirp Spread Spectrum Modulation
Ali Waqar Azim, Ahmad Bazzi, Raed Shubair +1
In this letter, we propose dual-mode chirp spread spectrum (DM-CSS) modulation for low-power wide-area networks. DM-CSS is capable of achieving a higher spectral efficiency (SE) re…
