Mobile Communications Systems
Run by School of Computer Science and Electronic Engineering
15 Credits or 7.5 ECTS Credits
Organiser: Prof Jianming Tang
Overall aims and purpose
This module will provide students with an in-depth understanding of current and emerging wireless transmission techniques, mobile communications systems and networks, with particular attention being focussed on operation principles and performances of mobile networks of different generations (2G, 3G and 4G) from layer 1 to layer 3. The future developing trends of mobile networks are also discussed.
• Introduction to fundamental concepts, terminologies and basic techniques involved in mobile communication systems. They include, for example, OSI reference model, signal characteristics in both the time and frequency domains, digital and analogue modulation, antennas, signal propagation, various multiplexing and de-multiplexing techniques, as well as spread spectrum. • Access media controls: Hidden and exposed terminals, near and far terminals, as well as wireless MAC techniques including SDMA, FDMA, TDMA and CDMA. • Wireless telecommunications systems including GSM, GPRS, UMTS/IMT-2000 and LTE/LTE-Advanced. • Mobile IP and mobile ad-hoc networks. • Wireless TCP congestion control
