Summary

The writing of this book was motivated by the authors' observation that convergence is requiring computer science students to gain a better understanding of communications concepts. The authors have therefore written a book that addresses this gap, delivering to the computer science student the key essentials in a thorough manner. The book walks the reader through the Fourier transform, analog and digital modulation techniques, multiple access communications, spread-spectrum communications, and source coding and channel coding. The book has already been used in the classroom and was met with great success in universities as an introductory text in electrical engineering programs.
