Adaptive Coded Modulation Performance and Channel Estimation Tools for Flat Fading Channels
Holm, Henrik (Dr. ingeniøravhandling, 0809-103X; 2002:18, Doctoral thesis, 2002)The need for spectrally efficient transmission on mobile and wireless channels is prevalent. A promising scheme for such transmission is adaptive coded modulation. In this thesis, techniques for assessing the performance ... -
Adaptive Coding and Modulation Techniques for HF Communication: Performance of different adaption techniques implemented with the HDL+ protocol
Carlsen, Martin (Master thesis, 2009)The main goal of this thesis is to present two good alternatives for the HDL+ protocol proposed for ratification in STANAG 4538, as this partially is restricted by a patent claims. The HDL+ protocol is used as a starting ... -
Adaptive Frequency Hopping with Channel Prediction
Flåm, John Torjus (Master thesis, 2006)The number of radio systems operating in the 2.4 GHz band is rising as a result of increased usage of wireless technologies. Since such devices interfere with one another, satisfactory co-existence becomes important. Several ... -
Aeroacoustics in a Flow Pipe with a small, variable-length Cavity
Krogvig, Anders Bakke (Master thesis, 2012)Pipes with corrugations or cavities are used in a wide variety of applications. In recent years the natural gas industry has experienced "singing" risers, where pipes transporting natural gas excite loud whistling sounds ... -
Akustisk analyse av snorking
Torsteinbø, Anders (Master thesis, 2007)I denne oppgaven har i hovedsak to teorier blitt undersøkt :1) er det mulig ved hjelp av ørepropper med høyttaler og mikrofon å detektere snorking og deretter spille tilbake lyder som får personen til å stoppe snorkingen, ... -
Alternative methods to generate a first-order directional microphone
Amengual Gari, Sebastia Vicenc (Master thesis, 2014)This thesis deals with the implementation and analysis of diferent methods to generate a first-order directional microphone for source location and noise measurement purposes. The methods analysed include a cardioid capsule, ... -
Ambient-light Photoplethysmography: - How can I tell your pulse from looking at your face?
Rustand, Åsmund (Master thesis, 2012)This thesis is an attempt to explore certain aspects of the subject called non-contact, ambient-light photoplethysmography, where we hope to reveal benecialproperties the technique may have. We have a clear focus on technical ... -
Amplifier for optimal reflection Coefficient of ultrasound transducer: A study of op amp based circuits for ultrasound transducers, targeted for low reflection Coefficient, high gain, and low noise
Mainou Gomez, José Francisco (Master thesis, 2012)Reverberation is defined as equally-spaced, bright linear echoes resulting from reflection from specular-type interfaces. They are provoked by the acoustic Impedance change between the tissue and transducer front surface. ... -
An exploration of user needs and experiences towards an interactive multi-view video presentation
Danielsen, Eivind (Master thesis, 2009)After a literature review about multi-view video technologies, it was focused on a multi-view video presentation where the user receives multiple video streams and can freely switch between them. User interaction was ... -
An FPGA-based implementation of the Conjugate Gradient Method used to solve Large Dense Systems of Linear Equations
Habbestad, Torstein (Master thesis, 2011)To find the solution to large dense systems have always been a very time consuming problem, this thesis tries to accelerate this problem by implementing an highly pipelined conjugate gradient method on an FPGA, it has been ... -
