1. Joint Source-Channel Coding using Trellis Coded CPM
Sammanfattning : The thesis investigates Joint Source and Channel Coding(JSCC) using combined Trellis Coded Quantization (TCQ) and coded modulation. First we investigate a JSCC scheme using combined TCQ/Trellis Coded CPM (TCQ/TCCPM). Based on the BCJR algorithm for trellis coded CPM, we derive an optimal soft decoding algorithm for the considered systems. LÄS MER
2. The effects of cellulosic fiber charges on polyelectrolyte adsorption and fiber-fiber interactions
Sammanfattning : The surface charges of cellulosic fibers contribute to several papermaking operations that influence the manufacture and final properties of paper. This thesis investigates the effect of the surface charges on wet-end chemistry, e.g. LÄS MER
3. Maximum likelihood sequence detection by using the SA(B,C) algorithm : state partition methods
Sammanfattning : .... LÄS MER
4. Joint source and channel coding using combined TCQ and CPM schemes
Sammanfattning : .... LÄS MER
5. Spectrally Efficient Continuous Phase Modulation
Sammanfattning : 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. LÄS MER
