Document Course Description
 

An introductory graduate course in digital communications. Major topics will include: modulation theory (Maximum A Posteriori decision theory, optimum receivers, vector-space representation of signals, probability of error analysis, energy and bandwidth efficiency), basic simulation principles, signal processing (block codes, convolutional codes, equalization), and spread spectrum communications (direct sequence, frequency-hopped). Examples will be taken from radio and satellite communications systems.
Document Textbook
 

Proakis, John G. (2001). Digital Communications, 4th. Edition. McGraw-Hill. ISBN# 0-07-232111-3

Supplementary material may be made available throughout the semester.
Document Software
The student edition of Matlab for Windows is suggested for those without access to the EE Graduate workstation laboratory.
Document Prerequisites
ECE 4634 - Digital and Analog Communications (or equivalent background). STAT 4714 – Probability and Statistics (or equivalent background)
Document Grading
 

Homework 20%
Midterm Exam 20%
Final Exam 30%
Project 30%

Scores will be normalized to assure proper weighting

Document Assignments
There will be approximately ten assignments, one per week except when another major assignment is (project or mid-term) due. Each assignment is due by the start of class on the date assigned. Late assignments will not be accepted.
Document Exams
There will be one in-class mid-term exam and one in-class final exam.
Document Project
Each student will undertake a research project focusing in detail on a relevant topic, algorithm or technique in the field of digital communications. A project proposal will be required early in the semester. An intermediate progress report and a final written report will be required later in the semester. Additional information on the projects will be made available as the semester progresses.
Document Honor Code
 

You may confer with your colleagues on interpretation and approach to homework problems, but the solutions should then be your own. All work submitted for examinations should be your own unaided work. You should write and sign the honor pledge on your exam: "I have neither given nor received unauthorized assistance on this assignment." Research projects should conform to accepted academic standards, and all outside sources of information should be clearly referenced. See Virginia Tech Graduate Honor Code for more information.
