LTE Enabling Technologies

Course 207

Summary:

WCDMA is the initial standard (1999) for the physical layer of the 3rd generation of mobile communication systems. Since then the standard is constantly evolving through Release 5 (HSDPA), Release 6 (HSUPA) , Release 7 (DL MIMO, IMS (IP Multimedia Subsystem)) and Release 8 (LTE-Long Term Evolution)

The course is focused on principles, technology, system architectures, evolution of standards, main applications and expected future trends in the field. The traditional technologies based on power controlled CDMA with RAKE as well as more advanced technologies based on multiuser detection, Adaptive Antennas, Multicarrier CDMA and Space-Time coding are discussed. A detailed discussion of the standard evolution will be presented.

Learning Objectives:

Upon completing the course, the participant will be able to:

understand CDMA principles and an insight into the advantages of using these techniques.
Compare CDMA/MC CDMA with traditional systems.
describe the relationship between the system performance, its complexity/reliability, and cost effectiveness.
asess the impact of existing and new coming technologies on the receiver structure. Implementation imperfections will be discussed.
discuss CDMA/MC CDMA applications in 3G land and satellite mobile communications, personal communications and cellular radio networks, indoor communications and wireless LAN.
Describe UTRA/UMTS/WCDMA FDD and TDD mode and other systems.
solve practical problems from an operator point of view (network resources allocation, control and management)
insight into ongoing activities in the development of the LTE wireless network

Target Audience:

This course is intended for postgraduate students, researchers, system engineers, R&D managers, and market planners who need to understand current approaches and evolving directions for personal and indoor communications, the 3G and incoming 4G land and satellite mobile radio communications, cellular networks and wireless LAN. It is also intended for engineers who are currently active or anticipate future involvement in the field.
