Apart from the efforts of myself, the success of Masters dissertation depends largely on the encouragement and guidelines of many others. I take this opportunity to express my gratitude to the people who have been instrumental in the successful completion of this project. I would like to express the deepest appreciation to my supervisor, \textbf{Dr. Satvir Singh}, Associate Professor, Department of Electronics \& Communication Engineering , SBS State Technical Campus, Ferozepur (Punjab), India, who has the attitude and the substance of a genius: he continually and convincingly conveyed a spirit of adventure in regard to research and scholarship, and an excitement in regard to teaching. Without his guidance and persistent help this dissertation would not have been possible. I can’t say thank you enough for his tremendous support and help. I feel motivated and encouraged every time I attend his meeting. Without his encouragement and guidance this project would not have materialized.

I am becoming increasingly present to the fact that research can indeed be an enjoyable and rewarding experience, despite the tedium and hardwork involved. This thesis is truly the culmination of his support, motivation, generous help and teachings. I can never forget the cheerful moments of my life when this charismatic personality accepted me as a research scholar. I must record my sincere gratitude to him for not only the great store-houses of knowledge he bestowed upon me but also for the chiseling and grooming I received in large measure in spheres of academic, professional and personal life. Without his constant chase and help, this work could not have taken this shape. I am pretty sure that his guidance would go a step beyond this thesis report and would be reflected in Doctorate Course and a couple of more publications of improved quality and of greater rigor and coverage, which I now look forward to.

Dr. Satvir Singh's mature research advice in the very initial stage never let me down in research throughout the longish period of research. I could learn the technique of organizing and writing quality research matter only because of his erudite teachings throughout the project. This in fact has left a permanent impression on my personality and written and verbal communication. I also express my great admiration and indebtedness for the manner in which he painstakingly carried out a thorough editing of our papers and the thesis, despite his overwhelming busy schedule and numerous responsibilities.

There are several other persons who made important contributions during this period. The guidance and support received from all the members who contributed and who are contributing to this project, was vital for the success of the project. I am grateful for their constant support and help.

First and foremost, I express my heartfelt gratitude to \textbf{Dr. Umesh K. Garg}, Associate Professor, Adesh Institue of Engineering \& Technology, Faridkot (Punjab) for motivating and pushing me towards PG Course, otherwise, this qualification might have been rather late.

My sincere thanks to my teachers \textbf{Mr. Vishal Sharma} and \textbf{Dr. Tejeet Singh} who used to guide us with their inspiring lectures of research methodolgy.

My sincere thanks  to \textbf{Dr. T. S. Sidhu}, Principal, SBS State Technical Campus, Ferozepur (Punjab) and to \textbf{Mr. Sanjeev Dewra}, Head, ECE Department, SBS State Technical Campus, Ferozepur (Punjab) and to \textbf{Mrs. Rajni}, Associate Professor, ECE Department, SBS State Technical Campus, Ferozepur (Punjab).

I express my gratitude to \textbf{Mr. Sureh Kumar}, \textbf{Mr. Darshan Singh}, Lab Staff at SBS State Technical Campus, Ferozepur for solving the Power problems and Wi-Fi problems occured during the course.

I wish to acknowledge the magnificent support I have received from my senior friend \textbf{Mr. Gagan Sachdeva} and my fellow friends \textbf{Ms. Shivangna Keer}, \textbf{Ms. Shelja Tayal} and my  brother \textbf{Atul} in the form of useful discussions throughout this work.

My sincere thanks to my friend \textbf{Ms. Gurimandeep Kaur} for clearing my doubts in \textsc{LaTeX} and making my writing part easier.

I am very grateful to my younger brother \textbf{Diwakar} who used to rush to the market for my printouts even late night and gave up playing games at Laptop for my research work and my friends \textbf{Ms. Nini}, \textbf{Ms. Pawan Supreet Kaur}, \textbf{Ms. Gurjeet Kaur} and \textbf{Mr. Hunny Sharma} for always appreciating and encouraging me towards research.

There are several other persons who made important contributions during this period, \textbf{Ms. Amandeep Kaur}, \textbf{Ms. Amrita Tayagi}, \textbf{Ms. Deepika} who used to sit with me when I used to work alone till late. I would thank \textbf{Ms. Navdeep Kaur}, my teacher who was just like a friend and finding us always busy in work advised us to even enjoy for sometime and relax.

Most profound regards to my mother \textbf{Smt. Meena Kumari} and my father \textbf{Sh. Anil Kumar}, who confined their needs all for my sake. Many a times, they took loan to meet my college expenses during my course of UG and PG studies; it is these sacrifices and constant blessings that kept me motivated and committed, until I reached this end.

Finally, I must thank GOD for giving me the environment to study, people to help, opportunities to encash and potential to succeed.
