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.
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..

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.
