I express my sincere thanks to Mr. Amit Sharma, Honorable Chairman of Amritsar College of Engineering & Technology (UGC Autonomous College, Accredited by NAAC, NBA Accredited Courses ), Amritsar, Punjab, India for his stimulating guidance, continuous encouragement and inspiration throughout the completion of the present work. I am extremely thankful to him for his motivation, and support throughout of my professional career.It has been for the few years that I'm teaching the subject ‘Wireless Communication systems’ to the students of Amritsar College of Engineering & Technology, Amritsar, Punjab, India, Department of Electronics & Communication Engineering and the current Book intend to act as a valuable text to that course so that the students can have an access to this course anytime. Although the communication aspects of this subject depend on the fundamentals of another interesting subject, communication engineering, I would strongly advocate the engineering students to go through the same in order to grow up adequate interest in this field. The entire book is broadly divided into 6 chapters, which, I consider to be most rudimentary topics to know the basics of this subject. In fact, this area is so vast and changing so fast over time, there is no limit of discussing the advanced level topics. The current focus has been therefore to deal with those main topics which would give the student sufficient exposure to this field to carry out further study and research. Initially, after dealing with the introductory concepts and the evolution of mobile communication systems till the present day status, the cellular engineering fundamentals are discussed at length to make the students realize the importance of the practical engineering aspects of this subject. Next, the different kinds of mobile communication channels is taken up and large scale path loss model as well as small scale fading effects are dealt in depth of understanding. Finally, different kinds of multiple access techniques are covered at length with the emphasis on how several mobile communication techniques evolve via this. The technological advancements in Wireless starting from GSM technology to LTE –Advanced systems are being discussed in this book to some finer details. During the process of developing the text book, I have received kind helps from my family, which I must acknowledge at the onset. I'm fortunate to have a group of energetic friends who have helped me a lot. It is for them only I could furnish this project. My sincere acknowledgment should also go to my parents who have nicely reciprocated my oblivion nature by their nourishing and generous attitude toward me since my childhood. Finally, about the satisfaction of the author. In general, an author becomes happy if he/she sees that his/her creation could instill certain sparks in the reader's mind. The same is true for me too. Once Bertrand Russell said “Science may set limits to knowledge, but should not set limits to imagination". If the readers can visualize the continuously changing technology in this field after reading this book and also can dream about a future career in the same, I will consider my endeavor to be successful. My best wishes to all the readers.
