Digital Communications (ENGN3226)

In 2023, this course is on campus with remote adjustments only for participants with unavoidable travel restrictions/visa delays.

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 (source encoder/decoder, channel encoder/decoder, digital modulator/demodulator and channel characteristics). The emphasis is on mathematical underpinnings of communications theory along with practical applications and emerging machine learning tools. Specific topics include:

• Review of Probability and Random Processes and Modelling of Gaussian noise process.

• Digital Modulation Techniques: Signal space analysis, BPSK, QPSK, QAM.

• Digital Demodulation & Detection Techniques: Correlator-demodulator, Maximum likelihood detection (MLD) in additive white Gaussian noise (AWGN), bit error rate (BER) performance.

• Channel Encoder/Decoder: Linear block codes, Cyclic codes, Convolutional codes, Viterbi algorithm.

• Information Theory and Source Coding: Source Entropy, Huffman Coding, Channel Capacity.

Matlab and/or Python-based programming environment is used in the analysis and design.

Learning Outcomes

Upon successful completion, students will have the knowledge and skills to:

1. Model digital communication signals and systems using appropriate mathematical techniques (e.g., probability, random process, signal-space analysis, constellation diagram, trellis diagram).
2. Analyse the performance of digital modulation schemes over AWGN channels and select and construct appropriate modulation schemes according to design criteria.
3. Characterise error-control codes and apply the encoding and decoding processes.
4. Compute source entropy and channel capacity and apply the Huffman coding technique.
5. Provide sound evaluation of practical digital communication systems in terms of their performance and complexity.
6. Simulate digital communication systems in a proficient and confident manner.
7. Apply engineering design practice in laboratory and project settings, individually or in a small team, and communicate the results effectively.

The ANU uses Turnitin to enhance student citation and referencing techniques, and to assess assignment submissions as a component of the University's approach to managing Academic Integrity. While the use of Turnitin is not mandatory, the ANU highly recommends Turnitin is used by both teaching staff and students. For additional information regarding Turnitin please visit the ANU Online website.
