| Modern Digital and Analog Communication Systems (Fourth Edition) | |
| Oxford University Press, Oxford (UK), 2009. |
Only the first seven chapters (out of fifteen) will be covered in ENEE 420. I had planned to have these seven chapters made available at cost through the Engineering Copy Center, located in Room 1123 in Glenn L. Martin Hall -- This would have obviated the need to purchase the entire book. Unfortunately, Oxford University Press will not grant permission to copy such a large portion of the book.
Therefore, the text has been ordered through the University of Maryland Book Center and the Maryland Book Exchange. In order to control cost I would suggest that you also shop online. Here are a couple of useful links

Also, some sites allow you to rent books while others will offer e-versions to be downloaded.
Additional material and information can be found in the following books and references with coverage similar to the text of Lathi and Ding:
| L.W. Couch, II Digitial and Analog Communication Systems (Sixth Edition), Prentice-Hall, Upper Saddle River (NJ), 2001. | |
| S. Haykin, Communication Systems (Fourth Edition), John Wiley and Sons, 2001 | |

The following book discusses the ways in which people and computer deal with information -- a highly readable and strongly recommended introduction to the digital age:
| R.W. Lucky, Silicon Dreams: Information, Man and Machine, St. Martin's Press, New York (NY) (1989). |
The next title contains a reprint of Shannon's original 1948 BSTJ papers that launched the digital age -- a must for all serious students of communications:
| C. E. Shannon and W. Weaver, The Mathematical Theory of Communication, University of Illinois Press, Urbana (IL) (1949). |
Communication is the process by which a message generated at one point is represented by a signal that is transmitted through an imperfect medium to a receiver, where a (hopefully accurate) estimate of the message is reconstructed. Topics to be covered include:
An understanding of analog-to-digital (A/D) and digital-to-analog (D/A) conversions, and of techniques for implementing these processes;
A presentation of continuous waveform modulation techniques (including amplitude modulation and angle modulation techniques), with emphasis on time and frequency representations, bandwidth requirements, power efficiency, coherent and envelope detection;
A discussion of intersymbol interference, and ways of combatting it through baseband pulse shaping;
A good appreciation of the time/frequency representation of signals and the effects of various kinds of modulation schemes on the same;
Insights into the role of random processes in communication systems analaysis, both as a model for system noise and as a model for message generation;

Homeworks will be assigned, collected and graded on a regular basis. Each assignment will contain ten (10) homework problems, but only three (3), selected at random, will be graded. The resulting grade will contribute for 10% of the grade for the course; see below for details. Homework assignments and answer sets can be found by simply clicking here.

Lecture notes on data compression, quantization, sampling and angle modulation will be made available. Comments and feedback welcome. These lecture notes may be periodically updated.

During the recitations, the TA will discuss the solutions to various exercises and review some key points of the course material. Notes used during these recitations can be found here.
The final grade for the course will be based on performance on homework assignments, two tests and a final exam; their respective contributions to the final grade are listed below. All examinations will take place in the classroom
