  2. 1. Advanced automotive radar front-end based on gapwaveguide technology

    Author : Qiannan Ren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MMIC; FMCW; gapwaveguide; packaging; automotive; dual circular polarization; antenna; imaging radar; polarimetric radar; Integration; LiP; MIMO;

    Abstract : The pursuit of higher levels of autonomous driving necessitates the utilization of advanced radar sensors that possess improved environmental perception capabilities. Consequently, next-generation automotive radars require sophisticated antenna systems with high efficiency, thereby making waveguide antennas a more viable choice. READ MORE

  4. 2. Robust Transceiver Design and Waveform Synthesis for Wideband MIMO Radar

    Author : Marie Ström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wideband radar; Robust analysis; Interference; Waveform synthesis; Transmit–receive filter design; MIMO radar;

    Abstract : This thesis deals with the problem of designing and synthesizing waveforms that are optimal, both in a signal-to-noise-and-interference ratio (SNIR), and in a system hardware design perspective, i.e., to synthesize time domain waveforms with a low peak-to-average power ratio (PAPR), or even constant modulus.

  5. 3. Sparse Array Architectures for Wireless Communication and Radar Applications

    Author : Navid Amani; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; base station antenna BSA ; sparse array; grating lobe; multi-user MU MIMO; multipath channel; mutual coupling; direction-of-arrival DOA estimation; MIMO radar; 5G; network theory;

    Abstract : This thesis focuses on sparse array architectures for the next generation of wireless communication, known as fifth-generation (5G), and automotive radar direction-of-arrival (DOA) estimation. For both applications, array spatial resolution plays a critical role to better distinguish multiple users/sources. READ MORE

  6. 4. Signal Processing Approaches for Interference Mitigation in Automotive Radar Systems

    Author : Muhammad Rameez; Mats Pettersson; Mattias Dahl; Saleh Javadi; Igal Bilik; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automotive radar; autoregressive modeling; digital beamforming; interference mitigation; machine learning; mutual interference; pulse compression; radar signal processing; signal reconstruction; Systemteknik; Systems Engineering;

    Abstract : Modern vehicles have several autonomous and semi-autonomous features, such as adaptive cruise control, lane keeping, adaptive headlights, and automatic emergency braking, ensuring a safe and comfortable driving experience. The vehicles typically rely on different sensors to "see" their surroundings and make decisions accordingly. READ MORE

  7. 5. On Massive MIMO for Massive Machine-Type Communications

    Author : Ema Becirovic; Erik G. Larsson; Emil Björnson; Ayca Özcelikkale; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : To cover all the needs and requirements of mobile networks in the future, the predicted usage of the mobile networks has been split into three use-cases: enhanced mobile broadband, ultra-reliable low-latency communication, and massive machine-type communication. In this thesis we focus on the massive machine-type communication use-case which is intended to facilitate the ever increasing number of smart devices and sensors. READ MORE
