Abstract:In the past two decades, wireless communication has grown with
unprecedented speed from early radio paging, cordless telephone, and
cellular telephony to today’s personal communication and computing
devices. These commercial wireless applications have had a profound
impact on today’s business world and people’s daily lives. The
growth and demand for wireless services will play a significant role
in the evolution of internet service from the current landline
system to wireless systems. One of the biggest challenges in
commercial wireless is satisfying an enormous and growing demand for
mobile communications with a limited and fixed amount of frequency
spectrum and power transmission. Expectations for mobile
communications have risen to the point where wireless quality of
service needs to equal or exceed that of wire line. The success of
early voice cellular systems had aroused the desire of consumers who
now require instant messaging, web browsing, electronic mail, and
many other types of services normally offered through wired internet
access but until just recently not truly practical over mobile
communication.
Hence, in order to fulfil the dream of mobile communication in the
future, some practical techniques such as smart antenna or Multiple
Inputs Multiple Output (MIMO) system essentially need to be
developed because these techniques based on a spatial processing are
able to improve the quality of transmission signals and increase
transmission rate and system capacity. Furthermore, modulation
schemes that tolerate coexistence in the frequency and time domains
need to be pursued and new multiple access techniques and spectrum
sharing algorithms need to be developed in order to serve all
existing of mobile communication services.
The aim of this research is to investigate an adaptive MIMO MC-CDMA
system including its complete architecture and adaptive
algorithms. This is to obtain a better understanding of the key
trade off in the next generation of mobile communication in aspects
such as realistic channel, user mobility effect, multiple user
access channels and multiple cell system.
This seminar will provide the system architecture and its adaptive
algorithms performed by the author. Both analytic and simulation
results will be presented. This presentation will end with the
future work toward the completion of PhD degree.
Biography:Peerapong Uthansakul received the Bachelor and Master degree of
Electrical Engineering from Chulalongkorn University, Thailand, in
1996 and 1998 respectively. From 1998 to 2001, he worked at the
Telephone Organization of Thailand as a telecommunication engineer
and then he worked as a lecturer of Suranaree University of
Technology, Thailand, from 2001-2003.
He is currently undertaking a PhD program under the supervision of
Professor Marek E. Bialkowski. His research interests include wave
propagation modelling, MIMO systems, mobile communications.
