"Link Adaptation Algorithms for MIMO-based WiMAX systems"

By

Mr. Tsz-Ho Chan


Abstract

In order to extend the coverage of wireless communication to metropolitan
scale, the Worldwide Interoperability for Microwave Access (WiMAX)
standard was developed and ratified as the IEEE 802.16d standard in June
2004. The standard defines an adaptive modulation framework which allows a
WiMAX system to communicate with various burst profiles according to the
link quality. The selection mechanism of a suitable burst profile is left
open for research.

This thesis devises a link adaptation algorithm for the MIMO-based WiMAX
systems. Cross layer design approach which combines both the signaling
level simulation in the PHY layer and the protocol level simulation in the
MAC layer are adopted. A MIMO simulation framework in which the PHY layer
metrics can be passed into the MAC layer under practical simulation
environment is also constructed using existing well-known simulation
tools. Evaluation showed that the proposed algorithm could achieve high
system throughput while keeping the packet error rate low.
