Next Generation Wireless Systems: Design and Analysis

 

The goal of this advanced/research course is to introduce students to the underlying theory, design techniques, and analytical tools for understanding and improving next generation wireless systems. A course will focus on beyond third generation (B3G) cellular standards such as Long Term Evolution (LTE) and IEEE 802.16 WiMAX. The course will first develop the basics required to understand the physical layer of B3G systems. This includes performance analysis of digital communication systems over fading channels, rate and power adaptation, and multiuser diversity techniques. It will then cover the LTE standard, its air interface, physical and logical channels, and physical layer procedures. Thereafter, advanced technologies that are likely to impact B3G standards such as cooperative communications and cognitive radio will be covered through a survey of research papers.

Digital communication over fading channels. Adaptation, multi-user systems, Long Term Evolution (LTE) standard overview. Comparison with WiMAX. Cooperative communications and relays: Relation to multi-antenna techniques, Cognitive radio.
