Digital Communications (ENGN6626)

This course presents the principles and techniques fundamental to the analysis and design of digital communication systems. It focuses on the basic building blocks of a digital communication system (channel encoder/decoder, digital modulator/demodulator and channel characteristics). The emphasis is on mathematical underpinnings of communications theory along with practical applications. Specific topics include:

• Probability and Random Processes: Probability distributions, Random variables, Random processes, Statistical averages, Correlation.
• Digital Modulation Techniques: Signal space analysis, BPSK, QPSK, QAM, bit error rates.
• Digital Demodulation & Detection Techniques: Correlator, Maximum a posteriori detection (MAP), Maximum likelihood detection (MLSD).
• Channel Encoder/Decoder: Linear block codes, Cyclic codes, Convolutional codes, Viterbi algorithm.
• Channel Characteristics: Wireline vs. wireless channels, Mathematical models for communication cannels, Characterization of multipath channels.
• Digital Communication Systems: Multiple Access techniques, TDMA vs. CDMA communication systems.

Simulink/Matlab is used extensively in the analysis and design.

## Learning Outcomes
