Opportunistic Radar Waveform Design in Joint Radar and Cellular Communication Systems

2015 IEEE Global Communications Conference (GLOBECOM), 2014
The ever increasing demand for spectrum, due to services with data rate requirements and ongoing exponential increase in the number of wireless devices, has pushed for new methods that allow for a flexible and shared use of spectrum among different wireless and radar systems.

Joint Communications and MIMO GMTI Radar Processing

2019 53rd Asilomar Conference on Signals, Systems, and Computers, 2019
This study develops a signal processing chain for a joint communications and multiple-input multiple-output (MIMO) ground moving target indicator (GMTI) radar receiver. Communications signals and radar returns are simultaneously received within the same spectrum.

Joint radar-communications waveform multiple access and synthetic aperture radar receiver

2017 51st Asilomar Conference on Signals, Systems, and Computers, 2017
Radar and communications systems are often deployed in already crowded environments. The growing demand for additional communications users in frequency bands previously reserved for radar users motivates cooperation between these systems. One solution to the problem of radar-communications coexistence is to develop joint systems that simultaneously ...

OFDM Pilot-Based Radar for Joint Vehicular Communication and Radar Systems

2018 IEEE Vehicular Networking Conference (VNC), 2018
With the large-scale deployment of connected and autonomous vehicles, the demand on wireless communication spectrum increases rapidly in vehicular networks. Due to increased demand, the allocated spectrum at the 5.9 GHz band for vehicular communication cannot be used efficiently for larger payloads to improve cooperative sensing, safety, and mobility ...

Joint FMCW Radar and 5G/6G Communications

2024 IEEE 35th International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC)
This paper considers how the 5G/6G parameterized communications signal can be integrated into and transmitted through a frequency-modulated continuous wave (FMCW) radar. The joint method can upgrade automotive, airport, harbour, marine, traffic control, etc., radars to relay orthogonal frequency division multiplexing (OFDM)-modulated signals. The 5G/6G

The Joint Radar Targets Detecting and Communication System

2006 International Radar Symposium, 2006
The combined radar system architecture for joint radar target detection and communication is considered. In this system we use complex quasi-continuous waveform of the big time-bandwidth product and duration with the combined modulation. This waveform is used in interrupted continuous wave radar technique.

Multi-Range Joint Automotive Radar and Communication using Pilot-based OFDM Radar

2020 IEEE Vehicular Networking Conference (VNC), 2020
To address the increasing communication demand driven by envisioned large-scale connected vehicle deployments, the dual use of the 76–81 GHz automotive radar frequency band for joint automotive radar and communication (JARC) system has gained significant interest given the wide and dedicated bandwidth.

Joint Power Allocation for Multicarrier Radar and Communication Coexistence

2020 IEEE International Radar Conference (RADAR), 2020
This paper examines the coexistence of radar and communication systems on a common frequency band using multicarrier waveforms. We consider a radar-centric sharing scenario where the radar needs to meet a minimum performance constraint, measured by the signal-to-interference-plus-noise ratio (SINR).

Joint Power Allocation for Radar and Communication Co-Existence

IEEE Signal Processing Letters, 2019
Co-existence of radar and communication systems based on cooperative spectrum sharing is of significant interest in recent years. This letter proposes two joint power allocation schemes for radar and communication spectrum sharing, where both systems use the same bandwidth with cross interference between them.
