Abstract
An integrated sensing and communications (ISAC) system using 5G NR waveform is implemented on a ZCU208 radio frequency system on chip (RFSoC) platform. Visualization of the data is performed using the PYNQ platform which facilitates data exchange between the processing system (PS) and the programmable logic (PL). The radar algorithm uses channel information in the frequency domain to detect a target’s range and speed. Both the communication and sensing aspects of the design is verified to work in field testings. A simple post-processing method using background subtraction is implemented to isolate the target information from the effect of background stationary objects.
Popular Abstract
Can you imagine if your Wi-Fi router can detect your current position? Or maybe you imagine a future where cars can drive itself through crowded traffic? The enabling technology for these features is sensing. For the longest time we have sensors to help machines understand its surrounding. However, sensors have a cost whether it be hardware, space, or computational complexity.

This is where the lucrative idea of ISAC comes in. ISAC can be considered as piggybacking a sensing system on top of a preexisting communication system. By smartly choosing algorithms and implementation method, information such as a target’s range and speed can be acquired for very small cost. Moreover, this concept could be implemented in a way that only minimal... (More)

The enabling technology for these features is sensing. For the longest time we have sensors to help machines understand its surrounding.

This is where the lucrative idea of ISAC comes in. ISAC can be considered as piggybacking a sensing system on top of a preexisting communication system. By smartly choosing algorithms and implementation method, information such as a target’s range and speed can be acquired for very small cost. Moreover, this concept could be implemented in a way that only minimal changes is required on existing hardware.

This work focuses on an field programmable gate array (FPGA) implementation of an ISAC system. Using an FPGA greatly reduces the latency in performing the sensing computations. This system can be used as a testbed for further testing and development of more advanced ISAC systems which will accelerate the development of the concept. The implemented design has been field tested and verified to work in basic scenarios. (Less)
