Transform coding has been extensively used for audio and speech compression applications during the past decades. A widely used transform is the real-valued Modified Discrete Cosine Transform (MDCT), which is employed in several state-of-the-art codecs such as the MPEG-1 Layer III (aka mp3) and AAC. An extension to this transform is the...

WLAN 802.11 (WiFi) and WPAN 802.15 (Bluetooth) operate in the same 2.4GHz ISM band. OFDM WLANs are designed to provide very high data rates, resilience to multipath and extended operating range. One of the main barriers to actually achieving the high data rates is the interference from the Bluetooth systems which is one of the main sources of...

In electronic warfare information about radio signals is gathered. Parameters as the direction-of-arrival (DOA) and the frequency can be estimated from sampled data received on antenna arrays. The objective of this thesis is to investigate the use of circular arrays for joint angle-frequency estimation (JAFE). A 1-D (azimuth and frequency) and 2...

This thesis proposes an algorithm to solve the issue of indoor localization using a source, reference receiver and mobile receiver placed in a convex room. The goal is determination of the position of the mobile receiver. The proposed algorithm consists of two localization techniques known from scientific literature: Time Difference of Arrival...

In tegenstelling tot conventionele radar -en radiosystemen kan de toepas- sing van een Software Defined Radio (SDR) grotendeels bepaald worden in software. Een SDR bestaat uit een RF-frontend, een paar ADC/DAC’s, een FPGA en een host computer. In de hostcomputer en de FPGA kan de functie van een SDR volledig worden geherdefini ?eerd, zonder dat...

Many techniques for array processing assume either that the system has a calibrated array or that the noise covariance matrix is known. If the noise covariance matrix is unknown, training or other calibration techniques are used to find it. In this thesis another approach to the problem of unknown noise covariance is presented. The factor...

Electronics systems in deep-submicron era face many new challenges. Increased intricacy of the manufacturing process will likely to increase the manufacturing defect while testing of those effect will be very challenging. Smaller feature size will also face new reliability issues due to phenomenas such as Joule heating and electromigration....

Radio frequency interference detection and mitigation for radio astronomy are bottleneck problems. Telescopes are becoming more sensitive therefore thresholds for detecting unwanted signals are becoming lower and telescopes have to deal with a big number of interference sources. When an unwanted signal is detected for radio astronomers it is...

Voor een home automation-systeem zijn vele draadloze implementaties beschikbaar. In deze thesis wordt onderzocht welke van de meestgebruikte implementaties van low-power draadloze protocollen het beste geschikt is voor de draadloze communicatie in een home automationsysteem. De implementaties die met elkaar worden vergeleken zijn Bluetooth,...

Optical flow algorithms present a way for computers to estimate motion from the real world. Applications like cloud motion, surveillance and robot eyesight are examples of this. The focus of existing research is mainly on either fast, but poor solutions, or slow but good solutions. In this thesis an approach to improve performance through...

Due to the increasing number of processors which are integrated in System On Chips (SOCs) the need for robust, highly configurable processors emerged. Preliminary research showed that commercial processors are not suited for many research projects due to the fact that they are closed source and they can not be modified. Open source processors on...

Efficiency of the Analog to Digital Converters (ADCs) has always been an issue of concern, especially, when it comes to sampling wide band signals which require extremely high sampling rates. As the systems with wide band signals are gaining the front position in digital communications, the need to find ways to reduce the sampling rates of ADCs...

VHDL and SystemC are both languages to describe or model circuits and systems. Reasons could exist for wanting to translate a model in VHDL to an equivalent model in SystemC. A system in SystemC can be needed for modeling a system with a software part, for a faster simulation, or because some tools only support SystemC. This thesis presents a...

In 2005, the WiMedia Alliance working with the European Computer Manufacturers Association (ECMA) announced the establishment of the WiMedia MB-OFDM (Multiband Orthogonal Frequency Division Multiplexing) UWB radio platform as their global UWB standard. It was also chosen as the physical layer (PHY) of high data rate wireless specifications for...

Integrated Circuit (IC) design complexity has increased radically since the first "hand-made" designs in the late 50s, with a few transistors. Nowadays, Very Large Scale Integration (VLSI) designs contains hundreds thousand, million or even billion transistors and not only the experience of the designer, but also Electronic Design Automation ...

It has been widely recognized that utilization of radio spectrum by licensed wireless systems, e.g., TV broadcasting, aeronautical telemetry, is quite low. In particular, at any given time and spatial region, there are frequency bands where there is no signal occupancy. There has been recent interest in improving spectrum utilization by...

In this thesis, we study a important class of structured matrices: "Hierarchically Semi-Separable" matrices, for which an efficient hierarchically state based representation called Hierarchically Semi- Separable (HSS) representation can be used to represent it with a small amount of parameters that are linear in the dimension of the matrix....
