Acknowledgments
I praise God for all His mercy and grace, the beauties of the world and the chance that he
has given us to discover its laws.
I would like to thank Dr. Mohammad Bagher Shamsollahi and Prof. Christian Jutten, the
supervisorsofthisresearch,fortheirexceptionalcharacters,thescientificandmoralguidance
ofthiswork,andtheiravailability. Thisresearchwouldnothavebeenaccomplishedwithout
their constant support. Christian and Mohammad have been far beyond supervisors for me
and I hope to carry the lessons that I learned from them in my personal life.
I sincerely thank my committee members: the president of the jury Prof. Jeanny H´erault,
thereviewersProf. AdrianvanOosteromandProf. Jean-Fran¸coisCardosofortheevaluation
of this work and their invaluable comments, and the examiners Dr. Massoud Babaie-Zadeh
and Dr. Vicente Zarzoso for their insightful feedbacks.
I would like to thank my beloved wife Maryam for all her love and patience during this
very first year of our marriage. This thesis would have been dedicated to her, if Mostafa
Chamran had not been a beau ideal for both of us.
I would like to thank my parents, my sister and my brother, for all their support and
encouragement throughout my life.
IowemuchofmysignalprocessinginsightstoDr. MohammadBagherShamsollahiandDr.
Ali Asghar Eftekhar, who gave me the courage to work with signal processing theories in
real world applications.
I would like to give my special thanks to Dr. Mohammad Ali Massoumnia, to whom I owe
all my knowledge of estimation theory. Many of the ideas of this thesis would not have
been developed without the wonderful and insightful course that I took with him in Sharif
University.
I would like to thank Dr. Vincent Vigneron, Dr. Gari D. Clifford, Dr. Dirk Hoyer, and Dr.
Raphael Schneider, for the fruitful discussions that we had and for providing some of the
fetal cardiac signals used in this research.
I also acknowledge Dr. Jeroen G. Stinstra and Dr. Charles D. Lawrence for permitting us
to use some of the figures in Chapter 3 for illustration.
I would like to thank all the teachers and professors that I have had throughout my life,
especially my first teacher, Mrs. Oskourchi, who taught me the Persian alphabet.
IshouldalsothankmydearfriendsandcolleaguesinSharifUniversityandGIPSA-lab,with
whom I shared many of the ideas of this research and who gave me invaluable feedbacks.
I would finally like to thank Shiraz University, the French embassy in Tehran, Sharif Uni-
versity of Technology, the French ministry of foreign affairs, the E´gide organization, the
Rhˆone-Alpes region, and Iran Telecommunication Research Center who provided us with
scholarships and research grants during this work.
