Textbooks
There are no required
textbooks for this class!
A set of lecture notes will be made available online --
Simply click here to go to
the lecture notes (Will be available in late July)
Additional material and information can be
found in the books and references in the Bibliography given below.
However, 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:
Course objectives
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. In a digital communication
system, the information--bearing signal is processed so that
it can be represented by a sequence of discrete messages.
While any information commodity can be digitized,
ultimately all information transfer is analog
as dictated by the particular communication channel/medium being used.
In this course we present techniques to address these issues,
and develop the basic principles that underlie
the analysis and design of digital communication systems.
The emphasis is on techniques for digital modulation and channel coding,
and their performance.
| Topics include:
| Detection of known signal in additive Gaussian white noise
(MAP and ML receivers)
|
|
| General bounds on the probability of error
|
|
| Binary case: Memoryless modulation schemes
|
|
| M-ary case: Memoryless modulation schemes (ASK, M-PSK, M-FSK)
|
|
| Symbols vs. bits
|
|
| Non-coherent detection and impact on performance
|
|
| Spectral density functions
|
|
| Information-theoretic aspects of digital communications.
|
|
| Trade-offs: Bandwidth vs. power
|
Prerequisites
|
| ENEE 420:
| Communication Systems (or equivalent)
|
|
|
ENEE 620:
| Random Processes in Communication and Control (or equivalent)
|
Required topics include (i) basic understanding of analog and digital
communications (e.g., analog and digital modulation, multiplexing, noise
and bit error rate), (ii) basic knowledge of signals and systems
and (iii) working knowledge of elementary probability
Grading system
The final grade for the course will be based on
two tests and a final exam; their respective
contributions to the final grade are listed below.
