我们提出了一个完整的模拟和实验框架的IEEE 802.11p。该框架的核心是一个基于软件定义无线电（SDR）的正交频分复用（OFDM）收发器，我们通过仿真、互操作性测试以及最终进行现场测试对该收发器进行了广泛验证。基于SDR的收发器提供了重要的好处：它提供了对所有数据的访问，包括物理层，从而可以更好地了解系统。基于开放和可编程的硬件和软件，收发器是完全透明的，所有实施细节都可以研究，如果需要，可以修改。最后，它使模拟和实验之间的无缝切换，从而有助于弥合理论和实践之间的差距。收发器的性能与独立的模拟和实验结果进行比较，我们强调其潜在的IEEE 802.11p网络的进一步研究，无论是在现场运行测试，以及基于模拟的开发新的物理层解决方案的工具。为了让其他研究人员可以访问该框架并允许复制结果，我们在开源许可下发布了它。
We present a complete simulation and experimentation framework for IEEE 802.11p. The core of the framework is a Software Defined Radio (SDR)-based Orthogonal Frequency Division Multiplexing (OFDM) transceiver that we validated extensively by means of simulations, interoperability tests, and, ultimately, by conducting a field test. Being SDR-based, the transceiver offers important benefits: It provides access to all data down to and including the physical layer, allowing for a better understanding of the system. Based on open and programmable hardware and software, the transceiver is completely transparent and all implementation details can be studied and, if needed, modified. Finally, it enables a seamless switch between simulations and experiments and, thus, helps to bridge the gap between theory and practice. Comparing the transceiver's performance with independent results from simulations and experiments, we underline its potential to be used as a tool for further studies of IEEE 802.11p networks both in field operational tests as well as for simulation-based development of novel physical layer solutions. To make the framework accessible to fellow researchers and to allow reproduction of the results, we released it under an Open Source license.
