Description
Future wireless communication aims to support high-quality high-speed services
such as Internet, video conferencing, and file transfer, at anytime anywhere without
wires. Due to the paucity of frequency spectrum, it is challenging to meet the everincreasing
demand of the number of users and data-rate requirement. Utilising
multiple antennas at both transmitter and receiver (known as MIMO antenna) and
orthogonal frequency-division multiplexing (OFDM) (the transmission scheme
currently used in IEEE802.11a and HiperLAN II wireless LANs standards) have
recently been demonstrated as the most outstanding techniques to providing highspeed
services over the air for low mobility users. The MIMO antenna technology
together with OFDM combines the use of the space and frequency dimensions to
enhance the transmission speed and has been recognised as the key to the future
success of wireless systems.
The objective of this project is to devise an optimal resource allocation method for
space-frequency transmission in a "downlink" scenario where a transmitter is
sending independent high-speed data to many users (e.g., from an access point to
many mobile terminals which can be a laptop or cell phone). The design aims to
make the best use of available system resources (i.e., bandwidth and power) for
achieving the requested Quality-of-Service of the users. None of research has been
done in the literature on the design in the respect of joint space-frequency multiuser
allocation mainly because adaptive resource allocation has to be performed on
orthogonal channels; yet conventional space-frequency transmission technique is
unable to accommodate signals in an orthogonal manner for a multiuser downlink
setting.
