As we enter the 6G era, wireless communication frequency bands are advancing towards higher ranges such as millimeter waves and terahertz, gradually overlapping with traditional radar sensing frequencies. Integrating sensing and communication on the same spectrum not only enhances the utilization of spectral resources but also alleviates the scarcity of traditional wireless spectrum resources. In simple terms, integrated sensing and communication technology involves adding radar-like capabilities (sensing) to our existing cellular mobile communication networks (communication), enabling the detection and tracking of surrounding objects such as drones, cars, or ships.
In a narrow sense, integrated sensing and communication refers to communication systems capable of ranging, speed measurement, angle measurement, imaging, target detection, target tracking, and target recognition, which was initially termed "radar-communication integration."
In a broader sense, integrated sensing and communication refers to communication systems that can perceive the attributes and states of all services, networks, users, terminals, and environmental objects, potentially surpassing the capabilities of traditional radar in sensing.
The overall architecture of the integrated sensing and communication system hardware platform is shown in Figure 1. In this setup, the SDR-LW/USRP-LW series software-defined radio hardware serves as the integrated sensing and communication transceiver. While transmitting signals to serve communication users, it also receives echo signals to enable the sensing of multiple targets.
The SDR-LW series is a high-performance SDR (Software-Defined Radio) standalone device launched by Luoguang Electronics, consisting of an onboard processor, FPGA, and RF front-end. By leveraging the collaborative operation of the Intel X86 processor and FPGA, the flexibility of the software-defined radio equipment is enhanced. The all-in-one design framework allows for the rapid deployment of integrated sensing and communication systems, whether indoors or outdoors.
