OverViewOverViewThe Aim of the project 
Design and develop a multimedia modem
Adopt
some possible new algorithms to improve its performance
Build a Lab testbed to test its performance
(Sorry but these are only open to NTU Campus Network now)
Research Groups Now we get several groups of students from NTU and Ngee Ann
Polytechnic engaged in the project.
DSL algorithms research
ADSL modem hardware implementation
ADSL performance testing
The main aim of the project is to design and develop a
multimedia modem. The development of Multimedia Networks and systems has strategic
importance to Singapore and is pertinent to the success of Singapore-ONE network.
Broadband network has two broad classifications: core network and access network. Core
network consists of high-speed switching system such as ATM and high-speed transmission
system such as SDH/SONET. In the core network we do research only in the area of
performance analysis and system integration. Major developmental activity in the core
network is undertaken by the large corporations and their research subsidiaries. As such,
we intend to focus our research on the access network which has a significant commercial
potential.
For the broadband access network, many technologies (HFC, SDV, FTTC, FTTH, HDSL, ADSL,
etc) have been proposed based on optical fibre, coaxial cable and unshielded twisted pair
copper cable. Singapore Cable Vision has selected cable modem and SingTel has chosen ADSL
modem. Both modems are in the introductory phase and their is a tremendous scope for our
contribution to the design in order to enhance the features and improve the performance.
Initially we like to concentrate on analyzing the pros and cons of various technologies,
with a view of selecting a most suitable technology considering the S-ONE requirements.
It's most likely that we shall embark on the fast developing technology, DSL. Various
coding, modulation and signal processing techniques are adopted in various DSL modems. DSP
is extensively used to equalize impairments and achieve coding algorithms. With our
expertise and strength in DSPs, we believe that we can achieve a successful design in this
fast developing technology. When we are successful in our R&D effort, we can look for
industry partners to commercialize the design.
