2. Towards Asymptotic Vector Quantization
Abstract : We study topics in source coding, and vector quantization (VQ) in particular. We approach VQ from two directions: a theoretical starting point based on high rate quantization theory, and a practical based on a database desription of the signal source. READ MORE

3. Quantization and Noise-Shaped Coding for High Efficiency Transmitter Architectures
Abstract : Three driving parameters in the development of transmitter technologies for wireless communication today is: energy efficiency, flexibility and footprint reduction. This thesis investigates the use of 1-bit oversampled signal representation, mainly as a power efficiency enhancement technique for the transmitter, but also as a path toward reduced footprint and increased flexibility.

4. Vector Quantization in Speech Coding. Variable Rate, Memory and Lattice Quantization
Abstract : This dissertation focuses on different quantization methods in speech coding. Variable rate quantization has the potential to substantially reduce the bit rate requirements in speech coding. READ MORE

5. Quantization of Random Processes and Related Statistical Problems
Abstract : In this thesis we study a scalar uniform and non-uniform quantization of random processes (or signals) in average case setting. Quantization (or discretization) of a signal is a standard task in all nalog/digital devices (e.g., digital recorders, remote sensors etc. READ MORE
