  2. 11. Array Processing Techniques for Direction of Arrival Estimation, Communications, and Localization in Vehicular and Wireless Sensor Networks

    Author : Marco Antonio Marques Marinho; Alexey Vinel; Henk Wymeersch; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DOA estimation; Array Interpolation; MIMO; Wireless Sensor Networks; Radio Positioning;

    Abstract : Array signal processing in wireless communication has been a topic of interest in research for over three decades. In the fourth generation (4G) of the wireless communication systems, also known as Long Term Evolution (LTE), multi antenna systems have been adopted according to the Release 9 of the 3rd Generation Partnership Project (3GPP).

  4. 12. Sub-Nyquist Sampling Impulse Radio UWB Receivers for the Internet-of-Things

    Author : Qin Zhou; Hannu Tenhunen; Li-Rong Zheng; Qiang Chen; Kari Halonen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultra-Wideband; impulse radio; receiver; energy detection; compressed sensing; sub-Nyquist sampling; Internet-of-Things; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : In the era of Internet-of-Things, the demand for short range wireless links featured by low-power and low-cost, robust communication and high-precision positioning is growing rapidly. Impulse Radio Ultra-Wideband (IR-UWB) technology characterized by the transmission of sub-nanosecond pulses spanning up to several GHz band with extremely low power spectral density emerges as a promising candidate.

  5. 13. Parameter Estimation for Mobile Positioning Applications

    Author : Parinaz Kasebzadeh; Fredrik Gustafsson; Gustaf Hendeby; Carsten Fritsche; Fredrik Gunnarsson; Jussi Collin; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The availability and reliability of mobile positioning algorithms depend on both the quality of measurements and the environmental characteristics. The positioning systems based on global navigation satellite systems (GNSS), for example, have typically a few meters accuracy but are unavailable in signal denied conditions and unreliable in multipath environments.
