“…In order to decrease the required development time we decided to use Matlab and Simulink for its implementation. Its design is pretty similar to the one detailed in [4], though several modifications were performed to make use of space-time diversity techniques.…”

“…In [4] we set the coefficient generation rate to frequencies that range between 2 and 4 KHz, so the shortest time the channel would remain almost constant would be 500 μs. Therefore, if the FPGA clock is set to 20 MHz, the number of cycles that the channel coherence would remain constant would be 500 μs/50 ns = 10,000.…”

The IEEE 802.11p standard has been optimized for low-delay small-bandwidth wireless communications to provide vehicular safety services. However, IEEE 802.11p transceivers can considerably improve their robustness by incorporating MIMO transmission methods. Moreover, multiple antennas can also be used to increase the data transfer rate of IEEE 802.11p transceivers, a requirement necessary to implement, for instance, non-critical safety applications. In this article we describe the design and development of a multiple-antenna IEEE 802.11p performance evaluation system made of two IEEE 802.11p software-based transceivers and two different, flexible low-cost FPGA-based multi-antenna channel emulators. Our channel emulators are able to recreate seven vehicular communication environments including highways, urban canyons and suburban areas. Using our performance evaluation system, we obtained performance curves showing that IEEE 802.11p can dramatically improve its performance by using multiple transmit and receive antennas. In addition, our channel emulators accelerated the performance evaluation task between 6 and 209 times compared to that of conventional software-based simulation approaches.
