In this paper a software-defined radio (SDR) implementation of a wireless transmitting (Tx) system is proposed. It is intended for real-time wireless transfer of time-critical control, diagnostics, and calibration data between a hardware-in-the-loop (HIL) test system and an automotive electronic control unit enabling novel HIL testing methods. The introduced SDR Tx system applies the wideband physical layer IEEE 802.11p and is designed for low Tx latency. Besides, it provides adaptivity in terms of a listen-before-talk mechanism that is mandatory required by the revised European spectrum regulations in the 2.4GHz industrial, scientific, and medical frequency band. Using hardware measurements concerning Tx latency and performance it is shown that the SDR Tx system offers an appropriate solution to evaluate the introduced real-time wireless application.
