Ramin Vali ID: 3196088 PhD Research Proposal
The ultimate goal of this research is to develop a
synchronisation system for a multiuser
wireless system that is primarily based on code division
multiple access technology. Wireless
communication, computer and sensor networks are expected to be
key technologies in this
century with a substantial impact on the economy and the
environment and numerous potential
applications. The inherent challenge of developing such a
network is simultaneously
accommodating many conflicting and demanding requirements, such
as security of informationtransmission, reliable but simple signal
processing algorithms and ultra-low power
consumption.
One of the most important requirements for the network is to
provide a secure transmission of
the information. In order to achieve this security a chaos-based
multiuser system will be
developed and investigated from synchronisation point of view. A
major problem associated
with the chaos-based communication, which is the sequence
synchronisation between
transmitter and receiver, will be addressed and solved in this
research work. In order to develop
the whole system, this research will incorporate the
investigation of the carrier and clock
synchronisation methods and techniques.
The system based on chaotic sequences will be compared with the
systems that use classical
pseudorandom sequences and possibility of the coexistence of
these sequences in the same
system will be investigated. For that purpose a theoretical
model will be developed and a
complex simulator that uses various sequences will be designed
and used for investigation.
This research project will be focused on the formulation,
theoretical analysis, simulation, and
experimental investigation of synchronisation techniques in
multi-user communication systems.
It is expected that the research will yield new synchronisation
methods and techniques which
will increase the reliability and security of information
transmission in wireless multiuser
computer, communication and sensor networks. These techniques
will be further developedinto reliable, simple and power-efficient
signal processing algorithms that could be applied
primarily in sensor networks. Finally, a transceiver prototype
for a multiuser wireless network
will be built to practically verify the newly developed methods
and techniques. The prototype
will ultimately serve to demonstrate the feasibility of
significantly reducing the transceiver
power requirements while maintaining computational performance
and speed, thereby solving
one of the most important challenges of wireless network
design.
