Special Issue Information

Dear Colleagues,

RADAR and wireless communication are the most common radio functionalities used by both civilian and military applications. Traditionally, these systems have been designed and developed in isolation from each other. However, the independent design of these systems wastes valuable spectral resources. Therefore, the spectrum shortages, combined with the emergence of novel applications requiring both functionalities, has inspired the research of joint radar and communication (RADCOM) systems in the same platform. This need will increase with 6G, which aims for supporting the convergence of the digital, physical, and personal domains. This requires expanding the functionalities of 5G to include the integration of radio sensing and communications in support of both hardware and spectrum-sharing. Furthermore, the merger of a sensing component into wireless communication networks has raised interest in recent years, and it may become a compelling design objective for 6G. However, the road leading to the joint sensing-communication network paradigm has significant challenges. Namely, the network synchronization, clutter suppression, hardware complexity, and waveform design still require significant research. Prospective authors are invited to submit original and unpublished work on the following research topics related to this Special Issue including but not limited to:

  • Novel waveforms for joint RADAR and communications.
  • Joint transmit and receive beamforming design for RADCOM.
  • Network synchronization schemes.
  • Hybrid analog-digital beamforming and sub-arrayed MIMO
  • Millimeter wave joint radar and communications.
  • Massive MIMO for RADCOM.
  • Efficient clutter suppression techniques.
  • Interference mitigation techniques.
  • Physical layer security for joint radar and communications.
  • RADCOM testbeds.

The integrated sensing and communication (ISAC) paradigm is being proposed for 6G as a new feature of the physical layer (PHY), for tackling dual-functional applications, i.e., demanding radio-sensing and communication functions, such as the Internet of Things (IoT) and autonomous driving systems. This work considers the integration of sensing and communications functionalities in a unique platform. To achieve this goal, the use of orthogonal space frequency block codes (SFBC) is proposed. SFBC code orthogonality enables both the separation of communications data streams at a user terminal and the estimation of target parameters. The SFBC enhances the communications link diversity without requiring channel state information knowledge at the transmitter and enable the virtual antenna array concept for enhancing the direction-finding resolution. The use of different SFBCs provides a tradeoff between achieved diversity and sensing resolution. For example, an Alamouti code, applicable for the case with two transmitting antennas, duplicates sensing resolution and achieves a diversity order of two while the use of a Tarokh code, applicable for a scenario with four transmitting antennas, provides a fourfold better resolution and diversity order of four. However, the code rate achieved with the Tarokh code is half of the one achieved with the Alamouti code. Furthermore, the unambiguous range is reduced since the bandwidth is divided to multiplex the different antenna signals. For its simplicity, good performance and reduced integration requirements, the method is promising for future ISAC systems. Full article
