1. Software Defined Radio Development (SDR) using a Network-On-Chip (NoC) based Rapid Prototyping Platform funded by ICT R&D Fund

Professor Dr. N. D. Gohar at NUST Institute of Information Technology (NIIT) has won a grant of Rs. 14.66 million from ICT Research and Development Fund for the design and development of a Software-Defined-Radio (SDR), using a Network-On-Chip (NOC)-based Rapid Prototyping Platform. This project, to be completed over a period of 4 years, aims to provide not only an NOC-based solution to SDR realization problem but also to develop research infrastructure and skilled manpower in this cutting-edge research area. The research and development stages will involve, besides three PhDs and six MS students, a number of Bachelor students working on certain sub-modules of an SDR as their final year projects. The successful design and development of a complete Network on Chip-based platform will also enable SDR computations at mobile base stations. In addition to ICT R&D Fund financial support, KTH will also provide Rs. 10 million for this project.

Software-Defined-Radio is a technology that is still in a state of infancy. The project focuses on developing a Scalable, Flexible and Modular Radio Systems Experimentation and Prototyping Platform (REXAPP) based on NOC (developed at KTH, Sweden), to provide basic foundation for SDR digital processing-a step forward in the development of future wireless communication systems.

2. Design & Development of Water Purification Technology Using Nanotechnology Funded by MoST

The primary objective of this project is to develop a practical, low cost and efficient process to decontaminate water and environment to the extent that the volatile organic compounds and inorganic compounds do not pose a threat to human health or the environment.

This research focuses on the following:-

  • A series of laboratory experiments will be conducted to assess the important photodegradable variables in water, like volatile organic compounds, light intensity, common ion effect, pH, humic acid effect, and catalyst, intermediate and final products.
  • To design a solar reactor for water decontamination and an on-site shallow pond photocatalytic reactor. To conduct a series of on-site experiments at some contaminated sites to assess the viability of the photoreactor processing of water.
  • To assemble a working prototype in order to demonstrate that water purification through photocatalysis is commercially viable, useful and easier for the rural areas of our country. This will require close integration with water purification industries to ensure that
  • The laboratory models are successfully developed,
  • The correct material are selected which is capable of detoxification under visible light
  • The material so developed may also be used for making self-cleaning glass for building
  • The material might be capable to maintain the aesthetic sense of vehicles and buildings
  • The material might be capable to degrade most of the volatile organic compounds not only from water but also from in/outdoor environment
  • The photocatalysts might also be capable to destroy carcinogenic cells in the human body
  • By coupling the photocatalysis process with chemical oxidation demand (COD) and biological sensors systems we can analyze the effectiveness of the system for volatile organic compound decomposition and for bacteria destruction
  • Arsenic and its compounds are proven to be hazardous for human being and animal.
  • This proposed project will be applied to decontaminate drinking water from arsenide and its compounds.
  • Energy storage and production of energy from solar spectrum is the focal research area in various scientific and research institutes. The newly developed visible light photocatalyst may also be investigated for solar energy production i.e. solar cell etc.

Dr. N.D. Gohar visited Royal Institute of Technology (KTH), Sweden from 1st July - 3rd September 2008. This visit was carried out in relation with the project titled "Software Defined Radio (SDR) Development Using Network-on-Chip (NOC) Based Rapid Prototyping Platform (REXAPP)". The project is a joint venture of Group for Research in ASIC and FPGA (GRAF) at NUST School of Electrical Engineering and Computer Science (SEECS) and KTH, Sweden. The visit was carried out on invitation of Dr. Ahmed Hemani from KTH, Sweden. The main purpose for the visit was to chalk out the detailed specifications for the project and problem statements and course work requirements for the PhD students. The visit also paved way for further collaboration between the two universities and couple of other project proposals have been developed. Another positive outcome of the visit is the agreement between the two universities to start a joint MS program in System-on-Chip from next year. A proposal has also been developed for that for formal approval. Overall, the visit has been very productive and successful.
