Integrated Sensing And Communication (ISAC) Workshop
Beyond 5G networks will provide value-added services beyond connectivity, supporting critical indoor and outdoor applications such as connected vehicles, autonomous factories, smart cities, smart roads among o
thers. In this context, a new emerging paradigm is that of Integrated Sensing And Communication (ISAC). The need for this paradigm is explained by the increasing use of the spectrum resources with a huge number of different sources, devoted to both sensing, like radars, and communication purposes. A number of possible architectures, all ascribable to the ISAC framework, can be devised, ranging from the mere coexistence of independent or nearly independent systems, to fully integrated systems, where both systems could use the same platform, same antenna, same waveforms etc.
If you want to learn more about this exciting topic, you are invited to attend the 3rd AESS workshop on ISAC.

3rd AESS Workshop on Integrated Sensing and Communications (ISAC)
November 6th , Sydney, Australia
Time: 14:00 – 17:00
Venue: ICC Conference room
Title: Introduction to the Integrated Sensing and Communications (ISAC) paradigm
Speaker and workshop chair: Maria Sabrina Greco, University of Pisa, Italy
Title: Sensing in Communications-centric Bi-Static ISAC Systems with Clock Asynchronism
Speaker: Andrew Zhang, University of Technology, Sydney, Australia
Abstract: Clock asyn
chronism is a central problem in integrating radar sensing into communication networks. It can cause ranging ambiguity and prevent coherent processing of dis-continuous measurements in the integration with asynchronous transceivers. Should it be resolved, sensing can be efficiently realized in communication networks requiring little network infrastructure and hardware changes.
This talk explores the techniques for resolving the clock asynchronism problem in the integration. We first introduce this problem in the context of a perceptive mobile network where sensing is integrated into mobile communications. We then review three classes of existing techniques, including using a global reference clock, single-node-based and network-based solutions. We elaborate on the single-node-based solution, which achieves sensing in a single node with multiple receiving antennas, exploring the common clock offsets across antennas. We conclude the talk by looking into open problems and future research op

Title: Delay-Doppler Plane Multi-Carrier Modulation: A Prom
ising Signal Waveform for Integrated Sensing and Communications (ISAC)
Speaker: Jinhong Yuan, University of New South Wales, Sydney, Australia
Abstract. In this talk, we first revisit linear time-varying channel’s representations in the time-frequency domain and the delay-Doppler domain. Then we briefly review recent development of orthogonal time frequency space (OTFS) modulation. Motivated by OTFS, we introduce a general multi-carrier (MC) modulation on delay-Doppler plane. A delay-Doppler plane orthogonal pulse (DDOP), which is essential for delay-Doppler plane MC
modulation waveform, is presented. We investigate the frequency domain representation of the DDOP, and compare the DDOP-based MC modulation with other modulation schemes. Various low complexity detection algorithms for the DD plane MC modulation are discussed. Interestingly, we show perfect orthogonality property of the DDOP with respect to delay-Doppler resolutions using its ambiguity function, which infers that the proposed MC signal waveform is suitable for integrated sensing and communications (ISAC).

Title: Index Modulation Schemes for Dual Function Radar Communications
Speaker: Elias Aboutanios, University of New South Wales, Sydney, Australia
Abstract: Dual Function Radar Communications (DFRC) aims to embed communication symbols into the radar e
missions. In this manner, DFRC strategies are radar-centric Integrated Sensing and Communication (ISAC) schemes. Index modulation (IM), which consider the indices of system configurations as a means to carry information, expand the boundaries of how information can be conveyed to a receiver. Recently IM schemes, which enable high data rates to be achieved, have been proposed for DFRC. In this talk, we discuss index modulation in MIMO radar, focusing on frequency-hopped radar waveforms.

Title: Embedding communications onto radar emissions – design methods, analysis, and experimentation
Speaker: Patrick McCormick, The University of Kansas, USA
Abstract: The utilization of the electromagnetic spectrum has been an increasing focus of research in recent years to improve the spectral efficiency of wireless radio frequency users. This efficiency can be gained via methods of coexistence with other users, or through the design of multi-functional emissions to perform different RF objectives. This talk will focus on the latter example, where we will discuss embedding communications information onto radar emissions. With the flexibility of commercially available software-defined systems and digital array structures, co-design of waveform modulation structures to perform radar and communications simultaneously is an increasingly relevant means to improve the spectral efficiency of a transmission. The flexibility of arbitrary waveform generation and digital arrays provides access to design degrees of freedom (such as time, frequency, space, and coding) that can be leveraged during the waveform design process. In this talk, three different designs of dual-function radar-communications transmissions will be highlighted with an emphasis on practical considerations regarding implementation
