A DSP system for hardware-in-the-loop testing of hands-free car kits

This work presents a hardware-in-the-loop (HIL) testing approach for hands-free car kits. The HIL system can be used to simulate the sound propagation within the car cabin. The proposed system is based on low latency and low complexity FIR filtering. It provides sufficient accuracy when employed in a measurement system for quality assessments according to the VDA specification for car hands-free measurements.
