2. 1. Low-Complexity Signal Processing for Speech Enhancement and Audio Analysis

   Author : Markus Lindroth; Benny Lövström; Ingvar Claesson; Fredric Lindström; Blekinge Tekniska Högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied Signal Processing; Tillämpad signalbehandling;

   Abstract : In real-time signal processing there is a constraint to finish processing of an audio signal before the next audio segment is received. This makes it important to have signal processing algorithms with low computational complexity while still maintaining high quality results. READ MORE

4. 2. Distributed Resource Allocation in Competitive Wireless Networks

   Author : Peter von Wrycza; Björn Ottersten; Gesualdo Scutari; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Signalbehandling;

   Abstract : The recent advancements in wireless technology and the developmentof efficient spectrum sharing strategies have had a great impacton today's communication systems. It is not uncommon that severalnetworks are deployed in the same area, each serving multipleusers who expect ubiquitous access to various voice andinformation services. READ MORE

5. 3. Sound Classification in Hearing Instruments

   Author : Peter Nordqvist; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sound Classification HMM Hearing Aid; Signal processing; Signalbehandling;

   Abstract : A variety of algorithms intended for the new generation of hearing aids is presented in this thesis. The main contribution of this work is the hidden Markov model (HMM) approach to classifying listening environments. This method is efficient and robust and well suited for hearing aid applications.

6. 4. Adaptive Coarse-grain Reconfigurable Protocol Processing Architecture

   Author : Mohammad Badawi; Ahmed Hemani; Zhonghai Lu; Zainalabedin Navabi; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive Architecture; Reconfigurable Architecture; Protocol Processing; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : Digital signal processors and their variants have provided significant benefit to efficient implementation of Physical Layer (PHY) of Open Systems Interconnection (OSI) model’s seven-layer protocol processing stack compared to the general purpose processors. Protocol processors promise to provide a similar advantage for implementing higher layers in the (OSI)'s seven-layer model. READ MORE

7. 5. Subband Beamforming for Speech Enhancement in Hands-Free Communication

   Author : Zohra Yermeche; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Beamforming; Speech enhancement; Subband filtering;

   Abstract : Speech enhancement by means of microphone array signal processing has a major role in voice communication applications such as audio-conferencing, hands-free telephony, voice recognition and hearing aids. In these communication scenarios, the speaker is positioned at a remote distance from the microphones, which causes problems of environment noise and interfering sound corrupting the received speech.
