“…Although most of the studied channel emulators are able to implement the whole system into only one FPGA, there are examples of channel emulators that distribute computing among different FPGAs (144). Furthermore, to fit the design into one FPGA, researchers have to save resources using different clever tricks, being one of the most recurrent the offline generation of the channel coefficients (137,140,141,143).…”

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.

This paper addresses the issue of designing scalable prototypes for multi input multi output (MIMO) wireless channel emulation. To date, emulators are extending single input single output (SISO) time based filtering techniques to emulate MIMO channels, which in turn requires quadratic increase in computational resources as the array size increases. In this paper, a new scalable approach for MIMO wireless channel emulation is presented. It is shown that for a 2x2 MIMO system, by performing channel emulation in the frequency domain, a reduction of up to 43 % in computations per output sample can be achieved as compared to traditional techniques. For higher order arrays, further reduction is possible. It is also illustrated that a linear growth in computational resources is attained through this scheme. The architecture is presented and synthesis results using an FPGA platform are discussed.
