    Author : Mats Bejhem; KTH; []
    Keywords : Machining Control; tool condition monitoring; in-process dynamic stability monitoring and control; optimisation of cutting conditions; MC; DSP; TCM; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : The objective of this work was the development of aMachining Control prototype system for turning, whichintegrates three fundamental aspects of Machining Controltechnology: Monitoring, Control and Optimisation. MachiningControl refers to the detection and automatic handling ofdisturbances in machining processes. READ MORE

  4. 2. Trellis Decoding: From Algorithm to Flexible Architectures

    Author : Matthias Kamuf; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; Signalbehandling; Signal processing; VLSI; Viterbi algorithm; trellis decoding; TCM; survivor path; flexibility; convolutional codes; ACS; ASIC; Elektronik; Telecommunication engineering; Telekommunikationsteknik;

    Abstract : Trellis decoding is a popular method to recover encoded information corrupted during transmission over a noisy channel. Prominent members of this class of decoding algorithms are the Viterbi algorithm, which provides maximum likelihood estimates, and the BCJR algorithm, which is a maximum a posteriori estimator commonly used in iterative decoding.

  6. 4. Spectrally Efficient Continuous Phase Modulation

    Author : Tommy Svensson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spectrum efficiency; Laurent decomposition; additive white Gaussian noise AWGN ; trellis coded modulation TCM ; non-linear channels; continuous phase modulation CPM ; maximum likelihood sequence detection MLSD ; distance spectrum; convolutional codes;

    Abstract : Spectrally efficient continuous phase modulation (CPM) systems and generalizations of CPM for wireless links are considered. Continuous phase modulation defines constant envelope phase codes, which are advantageous when using non-linear amplifiers. READ MORE

  7. 5. Systematic Antenna Design Using the Theory of Characteristic Modes

    Author : Zachary Miers; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Theory of Characteristic Modes; Antenna Design; Antenna; Characteristic Modes; Computational Electromagnetics; MIMO Systems; MIMO Antenna; MIMO; Mutual Coupling; Mobile Antenna;

    Abstract : The day Faraday moved a magnet in and out of a wire loop and detected the time-varying magnetic field, the first wireless transmitter / receiver system was created and the world was changed forever. However, it took almost fifty years for Heinrich Hertz to use Maxwell's equations and Faraday's insights in his professorship at Karlsruhe to create the first electromagnetic wireless communication system using a spark gap dipole transmitter and a loop antenna-based receiver.
