The current advances in the Intelligent Transportation Systems (ITS) reveal new solutions which are in need of validation in real-world deployments. The practicality, implementability, latency and robustness of such methods are key insights into their wide acceptance, and finally, absorption by standardization organizations. This paper discusses an approach to rapidly prototype newly proposed Wireless Access in Vehicular Environments (WAVE) algorithms based on the open source community and the emergence of Software Defined Radio (SDR). Concretely, this work details the practical deployment of a new adaptive channel estimation method in the context of IEEE 802.11p based vehicular communications. The development steps are illustrated and some challenges involved by real-world deployment (e.g. the phase tracking problem) are treated. Consequently, practical methods to solve the observed impairments are derived and implemented for real-time operation and validation.
