ELEC6217 Radio Communications Engineering

Module Overview

This course introduces the principles and techniques needed to design a wireless transceiver. We will cover the process needed to take the main principles of digital communications such as digital modulation and detection in noise. Through lectures and coursework, we cover the engineering tradeoffs needed to design a transceiver starting from a detailed performance specification.
