Discover how modern communication systems really work.
From mobile phones and WiFi to digital broadcasting and satellite links, the world relies on fast, reliable and efficient communication technologies. ELEC203 – Communication Systems: Principles and Applications give you the knowledge and practical insight to understand, analyse and design these essential systems.
In this module, you’ll explore the fundamentals of how information is transmitted, from analogue techniques like AM and FM through to the digital modulation schemes that power 4G/5G networks. You’ll learn how signals are sampled, digitised and shaped, how noise affects performance, and how engineers choose the right modulation and coding strategies for different scenarios.
Through problem-solving classes, interactive quizzes and a partially flipped teaching approach, you’ll build confidence applying theory to real engineering challenges. By the end of the module, you'll be equipped with the analytical tools used across the communications industry—whether you're interested in wireless systems, embedded devices, networking, or future technologies like IoT and smart infrastructure.
If you're fascinated by how data travels through the world around you, this module gives you the foundation to understand it—and the skills to help shape what comes next.
