Welcome to the Digital Communications (EE 6352) class. This course deals with the transmission of digital information from the transmitter to the receiver. Issues related to the transmitter, channel and receiver are discussed in detail.
Specifically, topics related to (a) formatting of digital information (b)
transmission (c) detection, and (d) performance evaluation will be considered.
Different transmission schemes are discussed and compared with each other.
\newline
The course material is divided into six sections. Short descriptions of the individual sections and the expected time durations are presented below: 
\newline
1. $Pulse$ $Amplitude$ $Modulation$ $(1$ $week)$
\newline
This section, even though is not quite on digital communications, presents
a quick review of sampling. It also addresses topics such as time division multiplexing, intersymbol interference, pulse shaping, and equalization that are common to digital transmission too.
\newline
2. $Baseband$ $Digital$ $Transmission$ $(2$ $1/2$ $weeks)$
\newline
This section starts with the issues related to analog to digital (A/D)
conversion; quantization and digitization, in the generation of PCM signals. Transmission and detection of PCM signals, and performance evaluation over a Gaussian channel are also discussed.
\newline
3. $Signal$ $Space$ $Representation$ $(2$ $weeks)$
\newline
This section introduces the signal space to represent signals used in a digital
transmission system. The construction of the signal space for a given
set of signals, and the use of the signal space to design and analyze the
performance of
 the optimal receiver are also explained.
\newline
4. $Digital$ $Carrier$ $Modulation$ $(3$ $1/2$ $weeks)$
\newline
In this section various digital carrier modulation techniques are discusses,
analyzed and compared with each other. A lowpass equivalent model is discussed along with the signal space to analyze various modulation techniques. Modulation techniques such as ASK, PSK,
FSK, QPSK, QAM and CPM are considered.
\newline
5. $Carrier$ $Demodulation$ $and$ $Performance$ $Evaluation$ $(3$ $1/2$ $weeks)$
\newline
This section deals with the detection and error rate performance of the modulation techniques discussed in sections 2 and 4 over an additive
white Gaussian noise (AWGN) channel. Both coherent and noncoherent detection techniques will be constructed and analyzed.
\newline
6. $Power$ $Spectra$ $of$ $Modulated$ $Signals$ $(2$ $1/2$ $weeks)$
\newline
In this section spectral variations of the modulation techniques are
computed and compared with each other.
\newline
The individual topics discussed in each section are outlined in the syllabus. 
\newline
\newline
$Textbooks$:
\newline
$Required$ $Textbook$: Digital Communications by John G. Proakis, McGraw Hill, ISBN: 0-07-051726-6
\newline
$Recommended$ $Textbook$: Digital Communications, Fundamentals and Applications by Benard Sklar, Prentice Hall, ISBN: 0-13-211939-0
\newline
\newline
Section 1 and the first part of section 2, which are relatively simple, fills
the gap between digital and analog communications. These topics have
been taken mostly from other textbooks such as the recommended textbook. 
The emphasis of the course
lies primarily in sections 3 through 6. In these sections the material is presented in a manner very close to that in the required text. 
\newline
\newline
$Format$: The material is presented using slides. Each slide is accompanied 
by an audio file. It is recommended that the student listen to the audio
portion along with each slide. 
\newline
\newline
$Pre-requisites$: EE 6349 (Random Processes). The students are expected to
be very familiar with the concepts of probability and random processes. The 
students are also expected to be familiar with concepts of analog communications. 
\newline
In order to determine the suitability, it is recommended that
each propective student go over the preliminary assignment which is totally
based on the pre-requisites. The course is intended for only those who can complete it without much effort.
\newline
\newline
$Grading$ $Policy$: 
\newline
Assignements: 15\%
\newline
Mid Term: 35\%
\newline
Final Exam (Comprehensive): 50\%
\newline 
\newline
$Assignment$ $and$ $Exam$ $Scedule$:
\newline
There are five homework assignements in the course. The first assignment will be
 due at the 
end of the second section (after 3 1/2 weeks). From that point on, there will
be an assignment due at the end of every section. The Midterm exam will be held
after 7 1/2 weeks into the semester, and the Final exam will be held within 
a week from the end of the last section. Both exams will be open book and time
limited for about 2 hours and 30 minutes each. Exams will be proctored, 
and upon completion the answer sheets need to be sent to the instructor by
e-mail, fax or by post.
