Radio hardware in-the-loop emulation for testing vehicular communication systems

In this work, a novel test concept Radio Hardware In-the-Loop (RadioHIL) for next generation automotive electronic control units (ECUs) with wireless interfaces is proposed. The resulting test environment is well suited for ECUs networking with wireless sensors, actuators, mobile terminals or even with other vehicles and infrastructure elements. The presented RadioHIL approach is based on Software Defined Radio (SDR) architecture. The first step for executing the RadioHIL concept is the implementation of a multi-standard waveform design for automotive relevant purposes. Therefore the model-based implementations of two compliant IEEE 802.11b and 802.11p SDR transmitters are outlined, which are of interest for vehicular wireless communication. The emulation concept is demonstrated on the Universal Software Radio Peripheral (USRP) SDR platform.
