Abstract:
Automotive radar and vehicular communication
are the two primary means of establishing an intelligent transportation system. However, both the systems are susceptible
to interference. The inter-vehicular interference significantly
affects the radar and communication performance, especially
in the dense traffic scenarios. In this work, we have shown that
lowering down radar range in dense traffic scenario provides
twofold advantages; (a) it reduces radar-to-radar interference
and, (b) it provides resources to support the vehicular communication. We propose a joint Radar-Communication (R-Comm)
algorithm which enables connected vehicles to use a fraction
of radar resources for vehicular communication based on the
traffic density. Also, two different schemes have been proposed
for R-Comm transmission in the sparse and dense traffic
scenarios. Further, through simulation results, it is shown that
R-Comm benefits both radar and communication systems
