1. On High-Speed Digital-to-Analog Converters and Semi-Digital FIR Filters
Abstract : High-speed and high-resolution digital-to-analog converters (DACs) are vital components in all telecommunication systems. Radio-frequency digital-to-analog converter (RFDAC) provides high-speed and high-resolution conversion from digital domain to an analog signal. RFDACs can be employed in direct-conversion radio transmitter architectures. READ MORE

2. Implementation of digit-serial filters
Abstract : In this thesis we discuss the design and implementation of Digital Signal Processing (DSP) applications in a standard digital CMOS technology. The aim is to fulfill a throughput requirement with lowest possible power consumption. READ MORE

3. System Modeling Using Basis Functions and Application to Echo Cancelation
Abstract : This thesis concerns modeling of linear and nonlinear dynamic systems, where the applied models can be described by basis function expansions. In the first part of the thesis, the investigated model (or filter) structures and parameter estimation algorithms are described. READ MORE

4. Sequential complex FIR-structure optimization
Abstract : Over the past 40 years, the area of digital signal processing and filtering has undergone a rapid development. Today, most of the filtering tasks, that before were performed by using analog technology, have been substituted with inexpensive and, often, more reliable and flexible digital solutions. READ MORE

5. Techniques for Efficient Implementation of FIR and Particle Filtering
Abstract : FIR filters occupy a central place many signal processing applications which either alter the shape, frequency or the sampling frequency of the signal. FIR filters are used because of their stability and possibility to have linear-phase but require a high filter order to achieve the same magnitude specifications as compared to IIR filters. READ MORE
