An automotive concept for vehicular communications is proposed that utilizes the potential of the roof area for antennas. Antennas are distributed in cavities and on shelves in the center and on the front and rear roof ends. The arrangement of antenn

The statistical study of target detectability is crucial in radar system design. In this regard, signal-to-noise ratio (SNR) of the received signal at the radar’s receiver is a key parameter and therefore every influence on SNR should be taken into

The bottleneck in OTA testing electrically large equipment is the large number of sources required for sufficient angular density. That is, if the sources are active. In that case, high-bandwidth, high-frequency equipment with excellent stability, pr

While traditional testing methods as conducted and open field tests have their limitations in terms of realism and repeatability of the scenario’s conditions, Over-the-Air (OTA) testing enhances the way that GNSS and mobile communications systems w

Ever since 4G, the role of MIMO antennas has become increasingly important in the increased sophistication of mobile communication systems. This has been and continues to be the subject of endless research, some of which has been incorporated into st

Antenna characterisation is usually performed by antenna pattern measurements in an anechoic chamber. Subsequently, a conducted test, the radiated two-stage or the wireless-cable method can be used for an overall system evaluation considering the mea

We devise a novel phase and time error measurement technique for 10 MHz and 1 PPS reference signals, based on Software Defined Radios (SDR) and Digital Signal Processing (DSP). The proposed measurement setup allows us to employ two synchronized type
