  2. 1. Multichannel Audio Signal Processing : Room Correction and Sound Perception

    Author : Adrian Bahne; Anders Ahlén; Lars-Johan Brännmark; Mathias Johansson; Peter Händel; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Audio signal processing; multichannel sound reproduction; equalizers; human sound perception; room correction; Elektroteknik med inriktning mot signalbehandling; Electrical Engineering with specialization in Signal Processing;

    Abstract : This thesis concerns and combines multichannel sound reproduction, digital room correction, audio signal processing, and human sound perception. It investigates perceived sound quality and new methods to improve timbral and spatial fidelity of loudspeaker-based multichannel sound reproduction in reverberant environments. READ MORE

  5. 3. On Interference Rejection in Wireless Multichannel Systems

    Author : Göran Klang; KTH; []
    Keywords : ;

    Abstract : To meet the growing demands for service provisioning usingwireless access, efficient utilization of the available radiospectrum is a key issue of great importance. To achieve highspectrum efficiency, use of spectral efficient modulationmethods in combination with tight physical channel reuse areanticipated in future cellular communication systems. READ MORE

  6. 4. Multicarrier Modulation and Coding for Multichannel Systems

    Author : Pål Frenger; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-code DS-CDMA.; Decision directed coherent detection; RCPC-codes; Parallel combinatory signaling; rate matching; OFDM; multichannel systems; Channel estimation; Multicarrier modulation;

    Abstract : In this thesis decision directed coherent detectors for single- and multicarriersystems employing an MMSE channel estimation technique is presented. Thedetectors are designed for Rayleigh fading channels and DQPSK or p/4-DQPSKmodulation and exploit knowledge of the fading process correlation. READ MORE
