Research groups

Communication and Signal Processing

Research is underway on the design and development of software that generates implementations and solves estimation problems using Kalman filters and its variants. From a high-level mathematical description of a state estimation problem, the software aims to generate code that computes statistically optimal estimate using the appropriate estimation filters. Also being developed are motion analysis algorithms to find relevant motion parameters based on available information, in the presence of relatively high error rates in low SNR conditions.

Distributed Databases

Some recent work carried out by the group members is in the area of data partitioning and allocation for distributed systems. In 2015, Agro Advisory System for cotton crop of north Gujarat region was developed. The current research interests include dynamic data partitioning and distribution, query processing architecture for streaming data, storage and configuration of tiered storage systems, and data blocking. The group members are exploring application domains like IoT, sensor network, and agriculture. This group is also interested in developing applications for biodiversity domain..

GPU Education Center at DA-IICT

Since April 2014, DA-IICT has been named a GPU Education Center by nVIDIA corporation – the world’s leading developer of Graphics Processing Units (GPUs) and one of the world leader in visual and High Performance Computing (HPC). Presently GPU based R&D activities at DA-IICT are primarily focused in the areas of Computational science and High Performance Computing more.

Next Generation Wireless Systems

Emerging wireless systems (super-3G, 4G, xG) will place greater demands on the base-band level, cross-layer design, and radio access technology. This research group focuses on designing and modeling state-of-the-art architecture for next generation wireless systems. Radio resource management, multi-hop communication, OFDM-based systems, dynamic spectrum access based on cognitive radio, and wireless multimedia streaming are the areas being investigated. Longer term vision of the group is to create an industry-backed center which contributes to the development of next generation wireless systems and standards.

Pattern Recognition & Image Processing

Multi-media systems, biometric authentication and automated medical diagnoses are just a few of the potential applications of ongoing work in image processing and pattern recognition. Specific research topics include super-resolution using motion cue, face recognition, and digital image watermarking.

Sensor Networks

Research is being carried out to apply this technology in various domains including, in particular, wildlife research, agriculture and animal health monitoring, and nuclear fusion reactor monitoring. Complete system design and development is being undertaken, including the design of energy-efficient protocols, localization algorithms, and routing algorithms for wireless sensor networks. The aim is to build a GPS-less wireless sensor network which can be used, for example, to track and monitor animals in a wildlife sanctuary. Work is also being carried out to develop a modular sensor network test-bed ‘CENSE’, consisting of a hundred nodes.

Speech Processing

Research is being conducted on various aspects, including in particular speaker recognition, focusing mainly on speech features based on linear prediction and Mel frequency cepstrum coefficients. The work is being carried out for several Indian languages. Speaker recognition research is further being explored in the area of spectral resolution problem associated with female speech, speaker classification, language identification, mimic resistance, and the effects of different coding standards on system performance. more…
