“…These simulations employ a theoretical description and analysis of the wave propagation effects by the use of a raytracing algorithm. The system simulator used therein was in turn verified and validated in terms of reference measurements of the simulated wave propagation scenarios and proofed very good agreement between measurements and simulations [15,16].…”

Abstract-In this paper a multiple input multiple output (MIMO) radio channel measurement system is presented that utilizes several software defined radio (SDR) platforms at the transmitter and at the receiver. The system hardware buildup and its calibration technique are presented. The channel measurement results are afterwards exploited for a special antenna synthesis method that was already proofed by raytracing channel simulations. The antenna synthesis method is applied to a mobile single and to a mobile multiple channel receiver. The resulting synthesized antenna systems are evaluated in terms of antenna radiation patterns and the corresponding channel capacities. The results reveal the superiority of synthesized antenna systems compared to conventional omnidirectional antenna systems in the considered urban street scenario. Moreover, the findings from the antenna synthesis based on dynamically measured MIMO radio channels confirm the results from the raytracing channel simulation based antenna synthesis.

“…Their approach is empirical in nature and consists of elaborate software tools packaged under the name Virtual Drive [18]. The results generated are highly useful but emphasize the fact that highly sophisticated simulations are the only means to research radar networks, motivating the derivation of analytical solutions.…”

Orthogonal frequency-division multiplexing (OFDM) communication-radar networks are systems where individual nodes use OFDM signals to both communicate and perform radar simultaneously. As a research subject, such networks are fairly new and lack some research covering fundamental limits. In particular, it is unclear how the reliability of the radar component is affected by a network operation, as several nodes might attempt to access the medium at the same time, thereby increasing interference and reducing the radar capabilities of individual nodes. In this paper, we apply the notion of outage (which was originally introduced for communication networks) to radar networks and introduce the outage probability as a performance metric. Using stochastic geometry, we are able to give tight bounds on the outage probability and demonstrate how this is useful for testing OFDM radar parametrizations and algorithms. It is possible to show that the outage probability is smaller than 1% for previously suggested OFDM radar parametrizations without having to resort to empirical methods.

“…Urban intersections and highways are two common scenarios where the number of vehicles in the transmission range can be large. The large number of vehicles in the intersection scenario is due to the high density of vehicles, while in the highway scenarios it is due to the larger coverage area which is a consequence of absence of buildings, few dominant scatterers, and high probability of line-of-sight (LOS) links [6], [7]. The high probability of LOS links and few dominant scatterers in the highway scenario implies that when two or more simultaneous transmissions occur they can arrive at the receiver with different angle of arrivals (AOAs) and narrow angular spreads.…”

In this paper, we analyze a carrier-sense multiple access (CSMA) system with all-to-all broadcast data traffic to assess the performance gain obtained by using multiple sector antennas and a receiver setup that can decode multiple packets simultaneously when packets arrive in narrow angle of arrivals. In the broadcast mode of IEEE 802.11p based vehicle-to-vehicle communications, acknowledgment messages are absent and a fixed contention window is used in medium access. As a result, the probability of multiple vehicles simultaneously transmitting a packet increases with the number of vehicles. In the case of a simultaneous transmission, a receiver with omnidirectional antennas receives power from all the transmitting vehicles and the probability of successfully decoding a packet decreases. This problem can be alleviated by using sector antennas when the simultaneously transmitted packets arrive at a receiver in narrow angle of arrivals. We show through analysis and simulations that the packet success rate (PSR) can be improved significantly by using the sector antennas setup instead of an omnidirectional antenna. Numerical results show that a several fold increase in PSR can be achieved in a setup with four sector antennas compared with an omnidirectional antenna when the density of vehicles is large.
