  2. 6. Detection for multiple input multiple output channels : analysis of sphere decoding and semidefinite relaxation

    Author : Joakim Jaldén; Björn Ottersten; Zhi-Quan Luo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunications; MIMO; Detection; Sphere Decoder; Semidefinite Relaxation; Telecommunication; Telekommunikation;

    Abstract : The problem of detecting a vector of symbols, drawn from a finite alphabet and transmitted over a multiple-input multiple-output (MIMO) channel with Gaussian noise, is of central importance in digital communications and is encountered in several different applications. Examples include, but are not limited to; detection of symbols spatially multiplexed over a multiple-antenna channel and the multiuser detection problem in a code division multiple access (CDMA) system.

  4. 7. Order restricted inference over countable preordered sets. Statistical aspects of neutron detection

    Author : Vladimir Pastukhov; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Constrained inference; Isotonic regression; Density estimation; Grenander estimator; Limit distribution; Neutron detection;

    Abstract : This thesis consists of four papers. In the first paper, we study the isotonic regression estimator over a general countable preordered set. We obtain the limiting distribution of the estimator and study its properties. Also, it is shown that the isotonisation preserves the rate of convergence of the underlying estimator. READ MORE

  5. 8. Interference Rejection and Channel Detection in Mobile Communication

    Author : Fredrik Nordström; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; detection of abrupt changes; WCDMA; Viterbi decoder; Kalman filter; co-channel interference; TDMA; EDGE; Mathematics; Matematik;

    Abstract : This thesis is devoted to statistical problems in mobile communication, in particular disturbance rejection and change detection are studied. Co-channel interference is a significant problem for systems based on TDMA, e.g. EDGE. READ MORE

  6. 9. Bayesian inference for detection problems in biology

    Author : Ronny Hedell; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PCR; Bayesian inference; Forensic DNA analysis; Syndromic surveillance; Bacillus anthracis; Markov chain Monte Carlo; Allele dropout; Bacillus anthracis;

    Abstract : This thesis is about different kinds of detection problems in biology: detection of DNA sequences in crime scene samples, detection of harmful bacteria in feed and food stuff and detection of epidemical diseases in animal populations. In each case, biological data is produced or collected in order to determine which DNA sequences, bacteria types or diseases are present, if any. READ MORE

  7. 10. Scan Statistics for Space-Time Cluster Detection

    Author : Benjamin Allévius; Martin Sköld; Michael Höhle; Paula Moraga-Serrano; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Scan statistics are used by public health agencies to detect and localize disease outbreaks. This thesis provides an overview of scan statistics in the context of prospective disease surveillance and outbreak detection, presents a novel scan statistic to deal with the type of zero-abundant data that is often encountered in these settings, and—perhaps most importantly—implements this and other scan statistics in a freely available and open source R package.
