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.
- 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: Source Entropy, Huffman Coding, Channel Capacity.
Advanced topics in digital communications are briefly discussed if time allows. Matlab is used extensively in the analysis and design.
Upon successful completion, students will have the knowledge and skills to:
1. Describe random variables and random processes in terms of their mean, variance, and correlation functions and characterize important random variables and processes.
2. Identify and analyse methods of digital modulation and compare their performance using signal-space analysis.
3. Explain receiver techniques for detection of a signal in AWGN channels.
4. Characterize error-control coding techniques and explain the working of Viterbi algorithm.
5. Compute source entropy and channel capacity and apply Huffman coding technique.
6. Develop an intuitive grasp of random variables and notion of random process and their characteristics.
7. Explain in simple words the working principles of basic building blocks of a digital communication systems.
8. Model digital communication systems using appropriate mathematical techniques (probability distributions, signal-space analysis, constellation diagrams, trellis graphs).
9. Provide sound evaluation of digital communication systems in terms of their performance and complexity.
10. Use Matlab for simulation of digital communication systems in a knowledgeable and confident manner.

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.
Workload10 hours per week is expected. approximately 36 hours of formal lectures, 2 three-hour computer labs, 3 two-to-three-hour hardware labs, 5 one-hour tutorials, plus adequate self-study, assignments and exam preparations.
