Book Description The renowned communications theorist Robert Gallager brings his lucid writing style to the study of the fundamental system aspects of digital communication for a one-semester course for graduate students. With the clarity and insight that have characterized his teaching and earlier textbooks, he develops a simple framework and then combines this with careful proofs to help the reader understand modern systems and simplified models in an intuitive yet precise way. A strong narrative and links between theory and practice reinforce this concise, practical presentation.

Digital Communication is one of the most needed for humans to record the history. The purpose of providing technology for humans aids to communicate. The purpose of a Communication System is to transport an information bearing signal from a source to a user destination via a communication channel.
Digital communication initially technologies are developed by separate network. However the networks are had to work together but in different times and signals.
The communication channels have only finite Bandwidth, non-ideal frequency response, the signal often suffers amplitude and phase distortion as it travels over the channel. We provide all the notes for students benefit for upcoming semester exams. For other subject notes contact www.

This is a rectangular representation of the polar diagram. On a polar diagram, the I axis lies on the zero degree phase reference, and the Q axis is rotated by 90 degrees. The signal vector’s projection onto the I axis is its.
