Advancements in electronics, wireless communications, and sensing technologies have made possible a multitude of smart sensing features in automotives. Integrating high-frequency sensors, digital signal processors and hardware accelerator engines on a single system on a chip (SoC) enhances sensing computation potential of radar sensors utilized in automotives. However, as the number of vehicles equipped with such wireless SoC sensors increases so does the likelihood of mutual wireless interference among these sensors leading to performance degradation and compromising safety of such systems. 

The main aim of the project is to design advanced digital signal processing modules for wireless radar sensor SoCs which can detect and mitigate mutual interference. High level system model of the proposed project showing various modules is presented in the above figure. Our interference-awareness and mitigation design will allow the use of interference mitigation module on an as-needed basis in the SoC. This means that interference mitigation processing chain will only be enabled when required which has the potential to enable power savings in the SoC.
