  1. 26. Robust Sound Field Control for Audio Reproduction : A Polynomial Approach to Discrete-Time Acoustic Modeling and Filter Design

    Författare :Lars-Johan Brännmark; Anders Ahlén; Mikael Sternad; Mathias Johansson; Rodney Kennedy; Uppsala universitet; []
    Nyckelord :Acoustic signal processing; equalizers; error modeling; feedforward control; interpolation; loudspeakers; multivariable filters; polynomials; robustness; sound fields;

    Sammanfattning : This thesis is concerned with the design and analysis of robust discrete-time filters for audio equalization and sound field control in real reverberant environments. Inspired by methods in polynomial control theory, a unified framework for acoustic modeling and filter design is developed. LÄS MER

    Sammanfattning : The requirements for next-generation wireless communications networks, particularly fifth-generation (5G) and beyond, are driven by at least three broad use cases. These include enhanced mobile broadband services to support extremely high data rates in terms of network or per user in both uplink and downlink, massive machine-type communications to accommodate massive internet-of-things applications, and critical machine-type communications to handle mission-critical applications that require ultra-high reliability and low latency.

  4. 28. Advanced Antennas in Wireless Communications : co-located & distributed

    Författare :Afif Osseiran; Ben Slimane; Andreas F. Molisch; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik;

    Sammanfattning : In a wireless radio network system, with an evolving standard, there is a need to increase system capacity due to the increase in the traffic demands, the higher data rate usage, and the need to further extend the coverage of the system. One possible solution is to use multiple antennas (co-located or distributed) for the radio links. LÄS MER
