| Acknowledgments
This work would not have been possible without the help of many people. First of all, I must thank my advisor, Dr. Michael Buehrer. His guidance was invaluable during and even after my time at Virginia Tech. I would also like to thank DRS Signal Solutions, Inc. for funding this work and providing the receiver hardware as well as for offering me a job right out of school. Numerous engineers from DRS-SS also deserve my gratitude. Tom Potter and Jeff Silvey, the two points of contact for the University program, were helpful in either answering any questions I had about the receiver or directing them to someone who could. Guy Zaybekian was an incredible help when it came to my questions about how the radio operates, as well as a more than capable teacher when it came to working with him professionally on a new software defined radio during my tenure at DRS-SS. Also, the entire engineering staff was very helpful when the provided a responsive and supportive audience for presentations on our work. Many of my colleagues at MPRG, all of whom I count as friends, also deserve their place here. Chris Anderson was indispensable when it came to solving problems relating to hardware. Swaroop Venkatesh and Jody Neel also knew were to point me when I had DSP questions and Max Robert was always around when I just needed to take a break. I must also thank John Keaveny, who was one of my good friends during both my undergraduate years at Saint Louis University as well as when I followed him out to Virginia Tech and took over his research project when he finished. I learned quite a lot from him in my first year at Tech. Lastly, I must also thank my wife, Sarah. Without her love and support this would have been a difficult process, and not nearly as much fun.
