Research Interests

Current research interests lie in estimation theory or filtering theory and its applications. Estimation theory or filtering theory is vast and rich in literature. It is central to a wide variety of disciplines, including control, communications, and signal processing. Estimating or filtering is the process of arriving at a value for a desired and unknown variable from certain observations or measurements of other variables related to the desired one but contaminated with noise. The goal is to estimate a desired output of a dynamical system by utilizing a measured output of the system but not the inputs or the disturbances that affect the system. Various estimation or filtering problems emerge depending on the properties sought for the estimation error, i.e. the difference between the actual and the estimated values of the desired output. Our aim is to study a number of estimation problems and relate them to one another. One of the important and celebrated problems in filtering is the Kalman filtering problem. Most of the available literature on Kalman filtering deals with what are known as regular filtering problems. Our study here considers the general filtering problems, the so called singular filtering problems.
