—Vehicle-to-vehicle (VTV) wireless communications have many envisioned applications in traffic safety and congestion avoidance, but the development of suitable communications systems and standards requires accurate models for the VTV propagation channel. In this paper, we present a new wideband multiple-input-multiple-output (MIMO) model for VTV channels(More)
| To make transportation safer, more efficient, and less harmful to the environment, traffic telematics services are currently being intensely investigated and developed. Such services require dependable wireless vehicle-to-infrastructure and vehicle-to-vehicle communications providing robust con-nectivity at moderate data rates. The development of such(More)
The development of efficient vehicle-to-vehicle (V2V) communications systems requires an understanding of the underlying propagation channels. In this paper, we present results on pathloss, power-delay profiles (PDPs), and delay-Doppler spectra from a high speed measurement campaign on a highway in Lund, Sweden. Measurements were performed at a This work is(More)
Preface It was in the summer of 2002 when the European Union launched the Sixth Framework Research Programme. One of the expected outcomes of this multibillion Euro initiative was Structuring, that is, tackling the fragmentation of European research on a large scale. The concept of the so-called Network of Excellence (NoE) was born, which was designed to(More)
— Joint time-variant channel estimation and multiuser detection are key building-blocks for wireless broadband communication for mobile users at vehicular speed. We propose an iterative receiver for a multi-carrier (MC) code division multiple access (CDMA) system in the uplink. Multiuser detection is implemented through iterative parallel interference(More)
The fading process in high speed vehicular traffic telematic applications at 5 GHz is expected to fulfill the wide-sense stationarity uncorrelated scattering (WSSUS) assumption for very short time-intervals only. In order to test this assumption we apply the concept of a local time– and frequency–variant scattering function, which we estimate from(More)
— We carried out a car–to–infrastructure (C2I) and car–to–car (C2C) 4×4 multiple–input multiple–output (MIMO) radio channel measurement campaign at 5.2 GHz in Lund, Swe-den. This paper presents first results on pathloss, power–delay profiles, and delay–Doppler spectra in a C2C highway scenario, where both cars were traveling in opposite directions. A(More)
SUMMARY Signals transmitted through multiple-input multiple-output (MIMO) wireless channels suffer from multiple-access interference (MAI), multipath propagation and additive noise. Iterative multiuser receiver algorithms mitigate these signal impairments, while offering a good tradeoff between performance and complexity. The receiver presented in this(More)
