Librería Portfolio

Showcasing the essential principles behind modern communication systems, this accessible undergraduate textbook provides a solid introduction to the foundations of communication theory. Carefully selected topics introduce students to the most important and fundamental concepts, giving students a focused, in-depth understanding of core material, and preparing them for more advanced study. Abstract concepts are introduced to students ´just in time´ and reinforced by nearly 200 end-of-chapter exercises, alongside numerous MATLAB code fragments, software problems and practical lab exercises, firmly linking the underlying theory to real-world problems, and providing additional hands-on experience. Finally, an accessible lecture-style organisation makes it easy for students to navigate to key passages, and quickly identify the most relevant material. Containing material suitable for a one- or two-semester course, and accompanied online by a password-protected solutions manual and supporting instructor resources, this is the perfect introductory textbook for undergraduate students studying electrical and computer engineering.

Software labs build on abstract theory, and give students a taste of practical industrial applications
Chapter introductions explaining real-world relevance of the material and a final roadmap for future R&D illustrate where communication theory sits within the bigger picture
Integration of MATLAB code fragments and labs throughout the text allows for immediate connection of theory to practice
Online resources include lecture slides and a solutions manual for instructors, example lab reports and code for instructors, and PowerPoint and JPEG versions of all the figures in the book
