Joint decoding of communication signals and target detection for coexisting RadComm systems

Abstract

With the advancement of communication and radar systems, many applications in the real-world, benefits in many ways. One of the focused applications would be the Adaptive Cruise Control (ACC) feature of a modern car. The main principle of the ACC works with the Frequency Modulated Continuous Wave (FMCW) radar system that is well-known for target distance judgement and velocity difference computation of both the vehicles in-front and back. In the current situation, ever since the boom on the Internet-of-Things (IoT), the spectrum seems to be much more congested which creates a shortage of bandwidth for other electronic systems. Therefore, the following project was proposed to join the functionally of both the FMCW radar and a Binary Frequency-Shift Keying (BFSK) communication scheme to be able to detect the target and communicate with it by sending data bits using a combined bandwidth. Moreover, the performance of the joint radar and communication (RadComm) system would be evaluated and studied to test the efficiency of the system.
