Joint Vehicular Radar and Communication System using Golay Sequences

This paper provides the design and simulation of a Joint Vehicular Radar and Communication System (JVRCS) to be used in the next-generation intelligent transportation applications. The suggested system uses a single waveform of Golay complementary sequences, which can both provide radar sensing and vehicle-to-vehicle (V2V) data transmission. Golay sequences offer optimum autocorrelated features, which enable the proper estimation of target range and velocity as well as maintaining communication. A MATLAB simulation framework is built where the vehicle transmits a unified waveform and processes the matching echo which is matched to the target using the method of the matched filtering and Doppler analysis to retrieve target parameters. Communication performance is also checked in the conditions of different noise levels to determine reliability. Simulation output indicates that explicit target detection and effective data transmission are possible when using the Golay-sequence-based waveform and this proves its compliance with the need to integrate radar-communication in next generation intelligent transportation and autonomous driving system.
