    @inproceedings{luebke2020a,
    abstract = {In this paper, an overall concept for a joint communication-sensing system at 77 GHz is presented with special focus on the communication part. To take advantage of the reduced interference between vehicles, code division multiplexing using direct sequence spread spectrum signals is applied. The system, which covers the whole signal processing chain, is introduced, explained and simulated using Simulink/Matlab software. A design, capable of spreading, modulating, including non-idealities of radio frequency-blocks and synchronization, is built up and evaluated. Additionally, a channel model is simulated in the software WinProp and integrated in the Simulink simulation. In consequence, a more realistic model compared to an estimation-based Rician-or Rayleigh channel model is realized. Furthermore, different modulation schemes, binary phase shift keying, 4- and 16-quadrature amplitude modulation, are investigated. The system is rated with respect to the bit-error-rate by applying additive white Gaussian noise. The functionality is verified as the the results match with the theoretical assumptions The system is further improved by building up a Rake-Receiver structure.},

    @inproceedings{voelkel2020,
    abstract = {In this paper, a scalable, fully digital adjustable,
    bistatic 60 GHz MIMO six-port transceiver is presented. The
    circuit features four independent transmitters and four six-port
    receivers on a single chip. The reference clock frequency of
    15 GHz is buffered and multiplied up to 60 GHz. The reference
    clock is also amplified and feed to an output port of the
    chip to render possible cascading multiple chips for massive
    MIMO applications. The receivers each include a VGA to set
    the reference power level, a LNA for amplification of the weak
    antenna signal and the six-port structure with three broadside
    linecoupler, a wilkinson-divider and four power detectors. The
    transmitters each include a switched-line phase shifter and a
    power amplifier. The whole circuit also contains an IQ-modulator
    which offers the opportunity for communication or correlation
    radar in future work. All settings for these components are
    adjusted by a 20 bit serial interface (6 bit address, 14 bit data).
    It is realized in 0.13μm CMOS logic and consists of a shift
    register, decoder and and an analog interface. The chip has a
    size of 4mm x 3.1mm and a power consumption of 960mW
    from a 3.3V power supply. A minimum input power of -22dBm
    is needed at the input clock. The transmitters deliver a maximum
    output power of 9.1dBm at 60 GHz. The phase is adjustable in
    a range from 0 to 325.4. The successful measurement results
    indicate, that the MIMO six-port transceiver is well suited for
    radar applications.

    abstract = {A 130 GHz fully integrated fundamental frequency transmitter (TX) module with 4.4 dBm single-ended measured output power in a 130 nm SiGe technology is presented. The transmitter achieves in measurement a phase noise of -88 dBc/Hz at 1 MHz offset frequency from a 130 GHz carrier and a tuning range of 17 GHz. Its relatively compact size, low power consumption and high output power, enables the TX module to
    be integrated into more complex D-Band transceiver modules for radar and imaging applications. Due to the available measurement equipment, it was only possible to measure the output power single-ended. The measured single-ended output power is 4.4 dBm. This corresponds well to a simulated differential output
    power of 8.1 dBm.Based on simulation results, the TX module can produce a maximum output power of 8.1 dBm. To the best of the author’s knowledge, the presented chip exhibits the highest output power fundamental frequency TX module among the recently reported state-of-the art chips in this frequency range.

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.},

    @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.

NB-IoT modules are expected to have a low energy consumption in order to allow for battery usage of more than 10 years and provide a wide coverage area.

    In our lab, we developed a lab system setup in order to measure the energy consumption of 3 NB-IoT modules from 3 different manufacturers using an LTE network mock-up model. Accordingly, we measured the energy consumption by the modules, and derived a data traffic dependent energy consumption model in order to estimate the corresponding expected battery lifetime. Furthermore, we measured the energy consumption per bit of the modules against the different number of uplink Narrowband Physical Uplink Shared Channel (NPUSCH) repetitions.

    abstract = {This paper presents a numerical study on the application of radar and communication (RadCom) sensor nodes operating in the frequency band from 57-64 GHz. The sensor nodes are embedded in the laminate of wind turbine blades, enable a quality inspection directly after rotor blade manufacturing as well as a structural health monitoring (SHM) throughout the service life of the blade. Given by a lack of dielectric properties for typical rotor blade materials, we have performed experimental studies on material characterization including glass fibre composites, balsa wood, infusion glue, etc. This material database serves as input for wave propagation simulations in a full scale 3D rotor blade model. The analysis also includes a parametric study on path losses as well as an optimal sensor placement strategy.},
