Communications System Laboratory offers an integrated approach to communications system teaching. Inspired by his students’ expressed desire to read background theory explained in simple terms and to obtain practical computer training, Dr. Kumar has crafted this textbook, ideal for a first course in communication systems.

The book merges theory with practical software and hardware applications. Each chapter includes the following components: a brief theory that describes the underlying mathematics and principles, a problem-solving section with a set of typical problems, a computer laboratory with programming examples and exercises in MATLAB® and Simulink®, and finally, in applicable chapters, a hardware laboratory with exercises using test and measurement equipment.

Covering fundamental topics such as frequency and bandwidth, as well as different generations of modulation including current 4G long-term evolution (LTE) techniques and future technologies like ultra wideband (UWB) systems, Communications System Laboratory provides engineering students with a deeper understanding of how electronic communications link the world.


"… suitable for electronic engineering students and young researchers to build up their initial knowledge in communications system analysis and design. … provides an insightful overview of the communications system’s structure, hierarchy, requirement identification, analysis, and performance evaluation. The main distinguishing point of this book is a great and well-structured offer of MATLAB® exercises associated to each communications system component design. Such an approach enables beginners, such as undergraduate or postgraduate students, to easily develop their experience and understanding of mutual relations and interdependencies of various communications system factors. It also facilitates quick development of MATLAB® simulations for designing and evaluating communications systems in realistic environments."

—Dr. Vladan Velisavljevic, University of Bedfordshire, Luton, UK
