Acknowledgments

This book was developed as part of my course EE 371C / EE 371C / EE 387K-17 Wireless Communications Lab taught at the University of Texas at Austin, along with the laboratory manual Digital Wireless Communication: Physical Layer Exploration Lab Using the NI USRP, published by the National Technology and Science Press. Many of my teaching assistants provided valuable feedback during the development of my course and books, including Roopsha Samanta, Sachin Dasnurkar, Ketan Mandke, Hoojin Lee, Josh Harguess, Caleb Lo, Robert Grant, Ramya Bhagavatula, Omar El Ayache, Harish Ganapathy, Zheng Li, Tom Novlan, Preeti Kumari, Vutha Va, Jianhua Mo, and Anum Anumali. All the teaching assistants ran the labs, worked with the students, collected feedback, and made suggestions and revisions, including examples and homework problems. Hundreds of students have taken the course and provided valuable feedback on various drafts of the book. They also asked thought-provoking questions that inspired revisions and additions in the text. In particular, I would like to thank Bhavatharini Sridharan for her positive feedback to get the book published with the material that I had. I would also like to thank Kien T. Truong for his assistance with the digital communication background chapter. I sincerely thank all my past students and teaching assistants for their support.

I would also like to acknowledge the support of my colleagues in developing this book. In particular, Professor Nuria Gonzaĺez-Prelcic provided a detailed review of all the chapters, including many suggestions and edits for the figures. Her overall help was invaluable. The Department of Electrical and Computer Engineering was helpful in supporting my teaching related to this book. I also appreciate the many colleagues who recommended my course to their students. Sam Shearman and Erik Luther at National Instruments provided much encouragement and support to get the book published, especially after they so graciously agreed to publish the accompanying laboratory manual.

The development of the course on which this book is based was supported by several groups. National Instruments (NI) made the course possible through its establishment of the Truchard Wireless Lab at the University of Texas at Austin. NI provided summer support that funded the endeavor and contributed countless hours of employee time. Several groups from UT at Austin, including the Department of Electrical Engineering and the Cockrell School of Engineering, provided teaching assistant support to develop and maintain the course materials. Working on the labs has inspired my research. I am pleased to acknowledge research support from the National Science Foundation, DARPA, the Office of Naval Research, the Army Research Labs, Huawei, National Instruments, Samsung, Semiconductor Research Corporation, Freescale, Andrew, Intel, Cisco, Verizon, AT&T, CommScope, Mitsubishi Electric Research Laboratories, Nokia, Toyota ITC, and Crown Castle. Their support has allowed me to train many graduate students who share my appreciation of theory and practice.
