Current Projects

Software Defined Radio Development using a Network-On-Chip based Rapid Prototyping PlatformProfessor 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.

The project has been funded by ICT Research & Development Fund.

Digitally Assisted Analog CircuitsDuring the last 15 years increase in the performance of digital ICs has become 150 times more than their analog counterparts. Since any real world system must compose of analog components, slow advancement of analog integrated circuits is now actually hindering the development of digital electronics. If these trends continue to occur, this problem is likely to become worse in the near future. Digitally Assisted Analog Circuits is a recently proposed method that has tremendous potential to nullify this effect. Basic idea is to simplify the analog circuits at the cost of decreased precision. This loss in precision is then modeled and compensated in the digital domain.

Completed Projects1- FPGA Based MIL-STD-1553 Remote Terminal/Bus Controller/ Bus Monitor

FPGA based MIL-STD-1553 Remote Terminal(RT)/Bus Controller(BC)/Bus Monitor(MT) implements the MIL-STD-1553 protocol on FPGA and allows the system to be configured as RT, BC or MT. This protocol is widely used in avionics especially the modern day fighter aircrafts like F-16 and Mirage. The project has been successfully completed and a prototype developed for it which is ready for field testing or deployment in a system.

This project was funded by Higher Education Commission.

2- FPGA based Portable Spectrum Analyzer FPGA based Spectrum Analyzer will be a signal analysis gadget with the maximum input signal frequency of 100 MHz. The offshoots of the project include Vibration Spectrum analysis in mechanical Testing Video Spectrum Analysis for various defense and commercial applications Spectral analysis of defense communications by Intel agencies Lab usage by various universities and developers

3- FPGA Based Remotely Controlled Internet Enabled Digital Signage SystemFPGA based Remote Advertisement System will be connected to the internet through which it will receive the configurations and data which will then be stored in EEPROM. The system will then accesses this data, decode it and display it onto an LCD monitor or an electronic billboard.

Digitally Assisted Analog Circuits is the latest research area that attempts to reduce the increasing gap between the advancement of digital and analog integrated circuits. During the last 15 years, increase in the performance of digital ICs has become 150 times more than their analog counterparts. Since any real world system must compose of analog components, slow advancement of analog integrated circuits is now actually hindering the development of digital electronics. If these trends continue to occur, this problem is likely to become worse in the near future.

Digitally Assisted Analog Circuits is a recently proposed method that has tremendous potential to nullify this effect. Basic idea is to simplify the analog circuits at the cost of decreased precision. This loss in precision is then modeled and compensated in the digital domain. Researchers in universities like Stanford and UC Berkeley have already demonstrated the tremendous potential of this research area.

The project aim is to apply this scheme in wireless technology and simplify the analog circuitry of existing technology improving its performance parameters like area, speed and power
