COURSE DESCRIPTION:
This course is designed to
explore current digital communications features. Fundamentals of sampling principles
and channel coding are utilized to develop common baseband and digital
modulation techniques (ASK, FSK, PSK, PCM, and delta modulation). Multiplexing
and multiple access networks are also analyzed. Techniques are applied in
design assignments with students designing to meet specified performance. MatLab is used to solve homework problems and
do the Team Design Project.

Each student is expected to
attend all of the scheduled classes if for some reason the student cannot make
a class the Instructor should be contacted in advance, if possible, to arrange
to turn in homework and to get the assignment for the following class. The
course includes homework problems, weekly quizzes on the homework due
that day, two semester exams and a Design
Project (Project report, PPT, and simulation files uploaded to Blackboard). Students are expected
to turn in all work on time; late work will be penalized.

Software:

Web Resources:
1.
The
Blackboard system
along with our course web site will be used to manage this course.
2.
Students
must submit their assignments into Blackboard for archival and grading. All work is to be typed (including
equations), drawings are to be computerbase, not scanned, hand written work. The best file format to use is MS Word (doc
or docx), but PDF can also be used.
Performance

Three
exams will be given covering several concepts each.

Exam Grading:
The purpose of the exams is to convey your
understanding of the material; therefore, it is important that you show your
work. Even if you feel that the solution
to a problem is obvious; you must still explain why it is obvious. Furthermore; if you are asked to solve a
problem using a given technique; then please use that technique; otherwise, I
have no way to judge your understanding of the technique being tested.
Homework policy:
Homework
will be assigned from the book as your primary preparation for the exams. We will review select homework problems in
class and you will be asked to work them on the board for a participation
grade. We will also incorporate design
problems / projects as appropriate to the material. These problems are designed to challenge you
to think beyond what the book has told you, and do real engineering. There may be more than one correct answer. Periodic
quizzes on the homework assignments will be the primary factors in your HW
grade. If you know in advance that you will be missing class please contact me
to make arrangements regarding homework.
If you understand how to do the homework problems you will have an
easier time with the Exams.
Distance Education Students:
The
course lecture notes and supplementary videos are accessible via links in this
syllabus. You should submit scanned
copied of assigned HW and your Exams via email.
Your project materials should be directly uploaded to Blackboard in the
designated assignment area. I will
arrange for a weekly, web enabled Q&A discussion once the class begins.
Distance Ed students should plan on attending the presentation sessions at the
end of the semester of the design projects.
Academic
Integrity:
Working
with classmates to study, resolve problems, and learn the material is expected
and encouraged during normal course work.
However, during individual evaluations (e.g. quizzes, exams, individual
projects, etc.) you are expected to comply with all standards of academic
honesty. You will be graded fairly, and
so your work should fairly represent your knowledge, abilities, and effort, not
that of others. Any breach of integrity
(including but not limited to: copying solutions, internet solutions, copying
from peers, claiming work or designs without proper citation, etc.), will not
only impact your ability to learn the material and my ability to help you
through proper feedback, it will result in academic penalty. Any individual found in breach of this code will
fail the afflicted assignment and will be asked to meet privately; any other
offenses will be referred to the Dean for further action, and could result in
penalties as severe as expulsion from the University.
