The basic concept of diversity; where two or more inputs at the receiver are used to get uncorrelated signals. aim this paper is an attempt compare some possible combinations diversity reception and MLSE detection techniques. Various combining techniques can be distinguished: Equal Gain Combining (EGC), Maximal Ratio (MRC), Selection Switching (SS).The simulation results shows that MRC give bet...

Circuit-switching can be particularly useful in optical multiprocessor interconnection networks, where it may be desirable to provide all-optical connections. Circuitswitched Banyan networks can be built from simple switching elements that do not have logical processing or buffering capabilities. Distributed, dynamic control can be provided to establish circuits in the network in response to th...

Performance of speech recognition systems strongly degrades in the presence of background noise, like the driving noise inside a car. In contrast to existing works, we aim to improve noise robustness focusing on all major levels of speech recognition: feature extraction, feature enhancement, speech modelling, and training. Thereby, we give an overview of promising auditory modelling concepts, s...

DONG, KE. Advanced Design Techniques in Linear Parameter Varying Control. (Under the direction of Associate Professor Fen Wu). To improve the analysis and control synthesis approach of linear fractional transformation (LFT) parameter-dependent systems, two types of non-quadratic Lyapunov function and switching control scheme are introduced and studied in this thesis. A gain-scheduled controller...

Introduction: Requirements of the physical layer in a photonic switching network include a high channel bandwidth for the throughput of ultra-high bandwidth signals, fast switching speeds and optical processing of switching control algorithms to remove the speed bottleneck imposed by electronic processing. Integrated-optic waveguide switches offer a channel bandwidth comparable to that of the f...

The PWM principle is used to control the output voltage of the three-phase inverters. There are many possible PWM techniques proposed in literature. Among these the space-vector PWM (SVM) method is an advanced PWM method and is possibly the best among all the PWM techniques for variable-frequency drive applications. The classical SVPWM which is used in the direct torque control of induction mot...

Network covert channels enable a policy-breaking network communication (e.g., within botnets). Within the last years, new covert channel techniques occurred which are based on the capability of protocol switching. There are currently no means available to counter these new techniques. In this paper we present the first approach to effectively limit the bandwidth of such covert channels by intro...
