“…an effective bandwidth of β 2 = B 2 /12 [9], is assumed. Due to the metallic chassis of the car, a typical value of 100 m 2 is used for RCS [4]. Thereby, the RCS accounts for the object's reflectivity characteristics influenced by its size, shape, and material.…”

This paper presents a localization approach which aims to detect and localize discrete mobile scatterers. Therefore, a network of spatially distributed transmitting and receiving nodes is used. The localization problem is formulated as a non-linear optimization problem and corresponding performance bounds for the positioning error are provided. To solve the optimization problem, an iterative non-linear least squares approach is used, following the algorithm of Levenberg and Marquard. The proposed localization approach is evaluated based on wideband measurement data. It is shown, that the localization of mobile scatterers can be achieved. A further evaluation reveals a strong dependence of the localization performance on the preceding link level parameter estimation. Particularly sparse networks are shown to be sensitive to rich multipath environments.

“…Other typical applications include the support for platooning and the typical technology is ITS-G5 or DSRC which are both based on IEEE 802.11p. More recently, this type of communiations is also addressed by LTE V2X by applying a D2D mode, and it naturally is considered for the upcoming 5G system [5], [6], [7], [8].…”

In this paper, we establish a simple model for the exchange of messages in a vehicular network and we consider fundamental limits on the achievable data rate. For a vehicular network, the exchange of data with other nearby vehicles is particularly important for traffic safety, e.g. for collision avoidance, but also for cooperative applications like platooning. These use cases are currently addressed by standards building on IEEE 802.11p, namely ITS-G5 and DSRC (dedicated short range communication), which encounter saturation problems at high vehicle densities. For this reason, we take a step back and ask for the fundamental limits for the common data rate in a vehicular network. After defining a simple single-lane model and the corresponding capacity limits for some basic multipleaccess schemes, we present results for a more realistic setting. For both scenarios, non-orthogonal multiple-access (NOMA) yields the best results.
