Prerequisites: Digital Communication
(EE7620) and Random Process (EE 4660).
Goals:
To serve as a continuing course of EE7620 by
exposing students to advanced topics in digital communication, such as
equalization,
CDMA based spread spectrum, orthogonal
frequency division multiplexing (OFDM), etc. Connections between
information theory
and advanced communication techniques will be
emphasized.
Course
Descriptions and Topics:
- Equalization: we study the problem of demodulation
and detection of signals corrupted by intersymbol interference.
- Optimum equalization method (MLSE) and
its performance.
- Suboptimum equalization
methods and their performances: Zero Forcing, MMSE, LMMSE,
DFE-MMSE.
- Orthogonal Frequency Division Multiplexing (OFDM): An alternative
for transmitting data in ISI channel.
- Capacity of frequency selective fading channel.
- OFDM: implementation of OFDM and its performance.
- Peak to mean average power ratio of OFDM.
- OFDMA.
- Spread Spectrum and Multiuser Detection
- Capacity of multiple access channel.
- CDMA and single user detection.
- Multi-user detection and its connection with equalization for
ISI channel.
- Diversity in Wireless Channels
- Diversity in point to point communication.
- Diversity in multi-user communication.
- Turbo Principle and Belief Propagation
Grading

- Project and presentation 30%
- One Midterm 20%
- Final 35%
