ELEC6214 Advanced Wireless Communications Networks and Systems
This module is taught in Semester 2. It is particularly aimed at equiping our MSc Wireless Communications and MEng Electronic Engineering with Wireless Communication students with advanced communication theory and technologies, vital for a successful career in digital economy. This is a key taught module for the MSc Wireless Communications and MEng Electronic Engineering with Wireless Communication programmes and is complementary to the semester 2 module, ELEC6216 Personal Multimedia Communications, which is hands-on coursework based. In particular, this module offers the students fundamental theory of wireless communications, which directly benefits their 'hands-on' practise in ELEC6216, in order to develop the vital transferable practical skills for working in the information industry. For undergraduate students, the prerequisites for this module are satisfied by having taken ELEC3203 Digital Coding and Transmission *or* ELEC3204 Wireless and Optical Communications. For postgraduate students, the prerequisites for this module are satisfied by the prerequisites of their programme. However, some additional background reading will be required for students who do not have a background in the topics covered by ELEC3203 and ELEC3204.
