  1. 16. TDMA for Low Sampling Rate IR-UWB Receivers

    Författare :Muhammad Adeel Ansari; Svante Signell; Ramir Eghbali; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In UWB communication sampling plays a key role in detection of the transmitted data. There are various methods of data transmission and detection at the receiver. Mostly, the detection methods are based on frequency domain methods. LÄS MER

  3. 17. Patients with chronic pain : quantitative and qualitative studies of treatment or rehabilitation at a pain clinic

    Författare :Andrea Hållstam; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background and aim: Chronic pain is a major problem, often with comorbidity of insomnia, mental disorders and limitations in function, activity and participation, all leading to poor quality of life. Patients describe their pain as unpredictable and ‘invisible’ thus influencing being and communication. LÄS MER

  4. 18. High-Speed Electroabsorption Modulators and p-i-n Photodiodes

    Författare :Robert Lewén; KTH; []
    Nyckelord :Optical communication; Fiber optic; Electroabsorption modulators; p-i-n photodiodes; transmission line; traveling wave; high-speed; microwave photonics;

    Sammanfattning : This thesis presents methods for optimization ofelectroabsorption modulators (EAM) and p-i-n photodiodes (PD)withrespect to high frequency (HF) performance. Differentreactive matching techniques are investigated such as lumpedmatching and integrated transmission line (TML) layouts includingoperation in the traveling-wave (TW) regime. LÄS MER

  5. 19. Ultrasound Communication through Thin Plates: Understanding the Channel

    Författare :Asra Ashraf; Jaap van de Beek; Johan E. Carlson; Magnus Sandell; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Sammanfattning : Ultrasound, composed of sound waves with frequencies above the human audible range, has become widely used in various technological fields for digital communications. In the past, acoustic and ultrasonic waves were employed in military and commercial un-derwater wireless communication systems due to their superior performance compared to electromagnetic waves.
