21. Sequential parameter and state learning in continuous time stochastic volatility models using the SMC² algorithm
University essay from KTH/Matematisk statistikAbstract : In this Master’s thesis, joint sequential inference of both parameters and states of stochastic volatility models is carried out using the SMC2 algorithm found in SMC2: an efficient algorithm for sequential analysis of state-space models, Nicolas Chopin, Pierre E. Jacob, Omiros Papaspiliopoulos. The models under study are the continuous time s.v. READ MORE

22. Implementation of a real-time Fast Fourier Transform on a Graphics Processing Unit with data streamed from a high-performance digitizer
University essay from Linköpings universitet/Programvara och system; Linköpings universitet/Tekniska högskolanAbstract : In this thesis we evaluate the prospects of performing real-time digital signal processing on a graphics processing unit (GPU) when linked together with a high-performance digitizer. A graphics card is acquired and an implementation developed that address issues such as transportation of data and capability of coping with the throughput of the data stream. READ MORE

23. Signal Processing for mmWave MIMO Radar
University essay from Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskapAbstract : This thesis addresses the design study, implementation and analysis of signal processing algorithms for a 79 GHz millimeter-wave Phase Modulated Continuous Wave (PMCW) Multi Input Multi Output (MIMO) short range radar; performed in IMEC research institute (Leuven, Belgium). The radar system targets high resolution performance with low power consumption in order to integrate a full MIMO radar transceiver with digital processor and antennas in a compact package featuring a size of 1 cm2.

24. Implementation and Evaluation of Spectral Subtraction with Minimum Statistics using WOLA and FFT Modulated Filter Banks
University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandlingAbstract : In communication system environment speech signal is corrupted due to presence of additive acoustic noise, so with this distortion the effective communication is degraded in terms of the quality and intelligibility of speech. Now present research is going how effectively acoustic noise can be eliminated without affecting the original speech quality, this tends to be our challenging in this current research thesis work.

25. Ultrasound induced cavitation and resonance amplification using adaptive feedback Control System
University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandlingAbstract : Acoustic cavitation in fluids using high powered ultrasound has been of great interest in industries and biomedical engineering. The need for high-intensity focused ultrasound (sound with frequencies between 20 kHz to 10 MHz) and modeling of such systems has drawn great attention in engineering. READ MORE
