A Detection Theoretical Approach to Digital Communications Using Autoregressive Process Shift Keying

Acknowledgements I thank my supervisor, Associate Professor Alfred Hanssen, for being everything that one can expect from a supervisor, and a little more. I thank him for sharing of his enthusiasm and energy as well as his knowledge, and for motivating me at the times when I needed it the most. I thank Ph.D. student Arnt-Børre Salberg, who has been working on the same project as me, for the time spent at rewarding discussions, for proposals and vital contributions to my understanding of the problems under study. His help has been greatly appreciated. I also thank the other students and members of staff that have contributed to the excellent learning environment and social environment at the Department. Special thanks go to my family, who has supported me throughout my student career. Moreover I thank my friends and colleagues, within and outside the University, for giving me plenty of opportunities to forget the world of Physics and Mathematics. In that concern, my deepest thanks go to Kjersti.
