Performance Evaluation of 802.16e in Vehicle to Vehicle Channels

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, the authors 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. They first introduce the non-stationary V2V channel models developed from empirical data. Then, they provide a brief overview of 802.16e and introduce three channel estimation schemes that apply to different scenarios.
