“…It covers how to distinguish the desired received signals from amounts of clutter and interference signals. The phase term introduced by multiple complementary phase code sequences, e.g., P3 code and P4 code, was multiplied to OFDM signals and the synthesis signals were resistant to multipath fading and intercarrier interference [42]. To improve the communication reliability and eliminate the communication-sensing mutual interference, Chen et al [43] proposed a novel code-division OFDM waveform via the product of a directsequence-spectrum-spread code vector and information symbols.…”

Integrated sensing and communication (ISAC) has been widely recognized as a key technology in future sixth-generation (6G) wireless networks, especially for emerging applications and scenarios demanding both high-performance sensing and communication functionalities. The ISAC technique has the potential of enabling sensing and communication functionalities in a single hardware platform, even sharing the same waveform, thus, achieving the reduced cost of hardware implementation and the efficient use of spectrum resources. In this paper, we commence with the discussion on sensing and communication at the current stage from the view of motivations, applications, and challenges. Then, we provide a comprehensive survey of the state-of-the-art approaches to the ISAC technique from the waveform design perspective. To be specific, we classify the waveform design methods into three categories, namely, communicationcentric waveform design, sensing-centric waveform design, and joint waveform optimization and design. In addition, potential research directions and challenges for future ISAC waveform design are outlined.INDEX TERMS 6G, integrated sensing and communication, communication-centric waveform design, sensing-centric waveform design, joint waveform optimization and design.

“…In order to obtain adequate synchronization accuracy, a variable symbol duration design was employed to enhance the security of the hidden communication signal by eliminating the cyclostationary features [144]. However, more effective coding and modulation schemes are needed to improve the communication throughput while achieving both low bit error ratio and high radar performance [145].…”

Joint radar and communication (JRC) technology has become important for civil and military applications for decades. This paper introduces the concepts, characteristics and advantages of JRC technology, presenting the typical applications that have benefited from JRC technology currently and in the future. This paper explores the state-of-the-art of JRC in the levels of coexistence, cooperation, co-design and collaboration. Compared to previous surveys, this paper reviews the entire trends that drive the development of radar sensing and wireless communication using JRC. Specifically, we explore an open research issue on radar and communication operating with mutual benefits based on collaboration, which represents the fourth stage of JRC evolution.

“…Modern RF synthesis techniques and digital signal processing resources provide radar waveform designers the opportunity for developing increasingly complex waveforms to meet radar system requirements. Examples of these types of waveforms include multi-frequency carrier OFDM [5][6][7], combined LFM/Barker codes [8,9] and combined LFM/PRN phase codes [10,11]. Traditional radar applications for these type of complex waveforms include marine radar [11], synthetic aperture radar (SAR) [12] and collision avoidance radar [13].…”

The design of a low cost, short range radar sensor based upon a novel phase coded linear frequency waveform is discussed in this paper. The radar sensor utilizes a novel waveform that is produced using digital frequency synthesis techniques. Digital frequency synthesis techniques enable the generation of repeatable, highly linear frequency sweeps and provide a means for accurate application of phase codes to linear frequency modulations. The work presented contains analysis of the component linear frequency and phase code modulations that form the compound phase coded linear frequency modulation. The resulting compound phase coded linear frequency modulation is compared with the component modulations to demonstrate the performance improvement that can be achieved by the combining of radar waveform modulations enabled by modern digital frequency synthesis techniques. The compound phase coded linear frequency modulation waveform shows improved range resolution and suppression of range sidelobes over the individual component waveforms. The phase coded linear frequency modulation shows an improvement of 13 dB over the linear frequency modulation and is only 2 dB less than the phase code. It also achieves a 5 and 10 nanosecond narrower mainlobe autocorrelation peak than the phase code and linear frequency modulation, respectively. A notional signal processing architecture of the waveform is simulated to demonstrate the ability to process the compound waveform. Experimental data collected from a direct digital frequency synthesis based arbitrary waveform generator is compared with the simulated waveform. The compound waveform model and the experimental results show good agreement.
