Iterative Channel Estimation for Wireless Communications

To My parents and family for their patience and support for all these years. iii ACKNOWLEDGEMENTS This thesis is by far the most significant accomplishment in my life, and it would be impossible without people who supported me and believed in me. Most of all I would like to express my sincere gratitude to my advisor, Professor Gordon L. Stüber, for his professional advice and guidance throughout my studies at Georgia Institute of Technology. The experiences in the Wireless Systems Laboratory (WSL) under Professor Stüber are the most valuable times in my career and life. I sincerely thank my co-advisor, Professor Ye (Geoffrey) Li, for his guidance and encouragement. I would also like to sincerely appreciate my thesis committee members, remarks and comments have made significant contributions to improving the quality of my thesis. I am also grateful to all the other professors from whom I have learned a lot during my studies at Georgia Tech. Zajic for their helpful discussions and encouragement. I would like to be very grateful to my lovely wife, HangEun, and lovely son, JinWoo, for their intense support, endless patience and great devotion. Without their unconditional support, patience, and sacrifice, I could have never made it this far. Finally not but the least, I cannot complete these acknowledgements without expressing how appreciative I am of all the love and affection that my parents have provided throughout my life. This thesis is dedicated to them.
