Vehicle to vehicle (V2V) communications have drawn much attention in the past few years. The IEEE 802.16e standard systems can be considered potential candidates for these applications due to their attractive features, like high data rate, mobility support, etc. In this paper, we evaluate the performance of an 802.16e system with the OFDMA air interface in two non-stationary vehicle to vehicle (V2V) channels: an open area high traffic density (OHT) channel and an urban (UOC) channel. We first introduce the non-stationary V2V channel models developed from empirical data. Then we provide a brief overview of 802.16e and introduce three channel estimation schemes that apply to different scenarios. Finally, we evaluate the performance of the 802.16e system over the proposed non-stationary V2V channel models. We show that the proposed channel estimation methods provide a good tradeoff between channel estimation accuracy and computational complexity. We also illustrate that system performance in non-stationary channels is more volatile than in stationary channels.
