  4. 2. A Signal Processing Approach to Practical Neurophysiology : A Search for Improved Methods in Clinical Routine and Research

    Author : Björn Hammarberg; Dick Stegeman; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Systemteknik; matched filter; asynchronous detection; Kalman filter; initialization; MHT; Wiener deconvolution; line source model; electromyography; needle EMG; motor unit potential; MUAP; mean fiber concentration; jitter; microneurography; C-fiber; spike sorting; Systemteknik; Systems engineering; Systemteknik; Signal Processing; signalbehandling;

    Abstract : Signal processing within the neurophysiological field is challenging and requires short processing time and reliable results. In this thesis, three main problems are considered.First, a modified line source model for simulation of muscle action potentials (APs) is presented. READ MORE

  5. 3. On Modulation and Detection Schemes for Low-Complexity Impulse Radio UWB Communications

    Author : Muhammad Gufran Khan; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UWB; RAKE; Transmitted reference; Energy detection; Channel measurements; BPPM;

    Abstract : Due to wealth of advantages offered by short range ultra wideband (UWB) technology, such as capacity improvement, fading reduction and localization, it has gathered a considerable attention. Distinct UWB qualities also pose many system design challenges like difficulties in using digital processing, complex channel estimation and different propagation characteristics. READ MORE

  6. 4. Successive Interference Cancellation in DS-CDMA Systems

    Author : Ann-Louise Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; group-wise detection; direct-sequence code division multiple access DS-CDMA ; multiuser detection; multirate schemes; weighted cancellation; successive interference cancellation;

    Abstract : There is every indication that direct-sequence code division multiple access (DS-CDMA) will be one of the multiple access schemes for the third generation wireless mobile systems. CDMA is a flexible multiple access method suitable for supporting many new services (speech, data, video, etc), which are becoming increasingly important for mobile communications. READ MORE

  7. 5. Metastases from Renal Cell Carcinoma. Recurrence Patterns, Detection and Management

    Author : Saeed Dabestani; Lund Obstetrik och gynekologi; []
