ELEC6217 Wireless Transceiver Design and Implementation

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. Through lectures and coursework, we cover the engineering trade-offs needed to design a transceiver starting from a detailed performance specification. The module uses Matlab as a specialist computation/simulation tool. Additionally, Labview is also introduced and used in this module.
