GNU radio and USRP2 as a universal platform for verification of wireless communication devices used in automotive applications

The nature of wireless communication protocols used in automotive industry (eg. TPMS - Tire Pressure Monitoring System, RKE Remote Key-less Entry or PEPS- Passive Entry & Passive Start) and fact, that transmission between remote sensor and main controller has to be received and correctly decoded, require sophisticated receiver systems. Complexity of systems installed in modern vehicles and variety of multiple conditions cause that verification and validation is the most difficult step of whole design process. Especially important part, that must be carefully checked, is behavior of a system in case of incorrect transmission. These false conditions should be repetitive, exact and comprehensive. Usage of Software Defined Radio (SDR) technique makes posible to fulfill all mentioned above requirements. This article describes utilization of SDR modeling with GNURadio to achieve flexible and very powerful Verification Platform for one-way automotive communication protocols. Description is focused on TPMS module however our solution works well for other protocols such as PEPS, RKE and similar.
