    abstract = {This paper presents several improvements of the energy-pattern based sequence detection (EPSD) algorithm for FSK-based single-phase power line communication (PLC) systems, in terms of complexity, reliability and synchronization. A time synchronization is presented which fulfills the well known task of synchronizing transmitter and receiver, but also helps to avoid transmissions in periods of rough noise conditions. The synchronization method is based on a maximum-likelihood approach that makes use of the phase of the mains voltage. Further improvements concern the codes used for the transmitted sequences as well as the combination of the information within both FSK carrier-frequencies in terms of equal gain and maximum ratio combining. Additionally an approach for a lowcomplexity frame synchronization is presented.

Our focus is the alignment of a passive listening sensor to a second active transmitting sensor in frequency, time, and waveform modulation parameters, just by observing the signals transmitted from the active sensor. We show that using a combination of inter- and intra-chirpsequence synchronization, the active sensor’s signal can be successfully de-ramped for fast-chirp-sequence waveforms with 275MHz of bandwidth. In addition, we discuss timing requirements and challenges, and characterize the remaining synchronization errors by an analysis of the IF signal data matrix of the de-ramped waveform.},

    @inproceedings{fuchs2020,
    abstract = {Automotive radar interference imposes big challenges on signal processing algorithms as it raises the noise floor and consequently lowers the detection probability. With limited frequency bands and increasing number of sensors per car, avoidance techniques such as frequency hopping or beamforming quickly become insufficient. Detect-and-repair strategies have been studied intensively for the automotive field, to reconstruct the affected signal samples. However depending on the type of interference, reconstruction of the time domain signals is a highly non-trivial task, which can affect following signal processing modules. In this work an autoencoder based convolutional neural network is proposed to perform image based denoising. Interference mitigation is phrased as a denoising task directly on the range-Doppler spectrum. The neural networks shows significant improvement with respect to signal-to-noiseplus- interference ratio in comparison to other state-of-the-art mitigation techniques, while better preserving phase information of the spectrum compared to other techniques.

    @inproceedings{dubey2020,
    abstract = {In recent years, the automotive radar systems has gained substantial interest for different applications of autonomous driving. The performance of most applications likes classification and tracking directly relies on accurate target detection. The state-of-the-art detection pipeline is vulnerable to multi-path reflections, clutter noise, interference from another radar and leads to false or ghost detections. To address this issue, an end-to-end target detection pipeline using a residual based U-Net architecture is proposed. In contrast to the conventional approach, the network directly generates the detection map from range-Doppler map. The network uses a generative adversarial training over multiple real world measurements. We demonstrate that the proposed network can learn effectively to detect extended targets and shows significant improvement under increased noise floor in comparison to the state-of-the-art detection techniques.},

In this piece of work, spectral scanning recordings were performed in the range of 410 to 870 MHz, covering wireless PMSE microphones at the 2018 F1 GP Brazil. The spectral scanning equipment was installed at two different locations, the international technical area for the TV stations (compound) with the UFABC semi-portable 6 GHz R&S spectrum analyzer and the TV Globo booth with APWPT’s semi-portable 3 GHz R&S spectrum analyzer in the middle of the pit line. There was a distance of about 2 km between the two locations. The equipment, controlled by specialized software. The radio spectrum was in use both by the technical team and the TV content production teams themselves, as well as the production, transmission and communication content between the various teams and their car drivers and a crew in a helicopter equipped with video cameras. In the three official days of the event from November 9th Friday to 11th Sunday, during many practice laps of the Interlagos racetrack, the official classification laps and the F1 GP Race itself, many links of audio PMSE equipment were recorded, the essential data of which were continuously monitored. Finally, the spectrum recordings were compared with TV Globe's coordination information. This reduced errors in the evaluation of the spectrum recording. Using previous reports since 2014 we can compare the number of microphones used in the Brazilian F1 GP and contrast with analogous recording procedures in Italian F1 GP at the same period.

    @phdthesis{ehlenz2020,
    abstract = {As part of a cooperative doctorate between the Friedrich-Alexander University of Erlangen

    Nuremberg and the University of Applied Sciences Trier, cables and transmission lines that

    users primarily perceive as electrical components have been researched similar to the

    established failure and dimensioning scheme of a machine element. The current work deals

    with the investigation of mechanically stressed cables and lines. Their use should get more

    reliable and the point of time for exchange of permanently moved lines be optimized. Cables

    in moving applications have highly complex electrical and mechanical requirements that are

    currently under-researched or insufficiently standardized. As it is common with other machine

    elements, operating time cannot be calculated. Especially with regard to Industry 4.0,

    unscheduled machine downtimes could become critical. With accelerated aging tests,

    manufacturers and users try to test their products in an increasingly shorter time-to-market.

    They use the alternating bending test, described in DIN EN 50396 to verify the cables’

    conformance. The research shows that the requirements of the standard are insufficiently

    described. After improvements of the test operations, which focused on the reproducibility, the

    alternating bending test defines the starting point of the multiphysical lifetime tests. Based on

    the findings of the parameter studies, a proposed standard for improving the test standard DIN

    EN 50396 was submitted to the responsible parent body. With the multiphysical recording of

    the course of damage during endurance tests, relevant wear patterns for moving lines can be

    identified. They form a novel phase model of the service life of mechanically dynamic loaded

    cables. The investigations show that structural changes and surface roughness of the copper

    material occur under prolonged mechanical stress before fracturing of the probands. Changes

    in the edge regions of the electrical material can be measured, making use of the skin effect. In

    conductors that are carrying high-frequency currents, the current density concentrates at the

    peripheric region of the conductor. An incipient roughness of the conductor leads to a change

    in the attenuation of a signal to be transmitted. In the run-up to empirical experiments,

    corresponding electrodynamical simulations on modelled conductors confirm the assumption.

    They show the increased current density at the peripheric area of a correspondingly aged, rough

    conductor. In subsequent empirical tests, an exchange time of test lines can be detected with insitu

    high-frequency attenuation measurement. The high-frequency measurement is a

    nondestructive, in-situ diagnostic option for mechanical cable wear. The measurement method

    is suitable for the commercial use of a later cable monitoring system, in which lines can be

    evaluated during their operation with regard to estimated remaining lifetime. The research

    results contribute to a predictable product life of the mechanically loaded electrical lines and

    thus to increased reliability in many industries.
