2. 1. On Parameter Estimation and Control of Time-Varying Stochastic Systems

   Author : Bengt Lindoff; Matematisk statistik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistics; Adaptive Predictive Control; Adaptive Stochastic Control; Dual Control; Convergence Analysis; Quadratic Forms; Forgetting Factor; Recursive Least Squares; Recursive Estimation; Linear Systems; Time-Varying Stochastic Systems; operations research; programming; actuarial mathematics; Statistik; operationsanalys; programmering; aktuariematematik;

   Abstract : This thesis is about parameter estimation and control of time-varying stochastic systems. It can be divided into two parts. The first part deals with an estimation algorithm commonly used when estimating parameters in time-varying stochastic systems, the Recursive Least Squares (RLS) algorithm with forgetting factor.

5. 3. Stereophonic Acoustic Echo Cancellation: Theory and Implementation

   Author : Peter Eneroth; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stereophonic Acoustic Echo Cancellation; Filterbank; Two-Channel Fast RLS; Two-Channel Frequency-Domain Adaptive filtering; NLMS; Electronics and Electrical technology; Audio Coding; Elektronik och elektroteknik; Signal processing; Signalbehandling; Subband;

   Abstract : The thesis treats theory and implementation aspects for stereophonic acoustic echo cancellation. In Paper I a complete implementation of a stereophonic acoustic echo canceler based on the two-channel fast recursive least-squares algorithm is presented. READ MORE

6. 4. Adaptive Forgetting through Multiple Models and Adaptive Control of Car Dynamics

   Author : Peter Andersson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive forgetting; Multiple models; Adaptive control; Car dynamics;

   Abstract : A new recursive identif ication method, Adaptive Forgetting through Multiple Models - AFMM, is presented and evaluated using computer simulations. AFMM is specif ically suited for identification of systems with jumping or rapidly changing parameters. READ MORE

7. 5. Teleconferencing, system identification and array processing

   Author : Per Åhgren; Peter Stoica; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal Processing; Signalbehandling;

   Abstract : The area of teleconferencing has long yielded great interest in the signal processing community. The main reasons for this are probably the huge interest from the industry and the challenging problems of the topic. The problems of teleconferencing are relevant for several different disciplines in signal processing. READ MORE
