Research Interests

My research interests belong to the general area of information and communication theory. More specifically, I am interested in the coding of information-bearing signals for transmission over noisy communication channels. This problem is addressed at two levels: One objective is to understand and investigate the Shannon theoretic aspect of this problem -- i.e., to determine the fundamental limits to how efficiently one can encode information and still be able to recover it with negligible loss. Another vital objective is to develop new techniques that are appropriate for current and near-term developing technologies -- e.g., achieving reliable transmission of multimedia signals (text, data, speech/audio, image, and video) over wireless communication channels for the establishment of mobile personal communication systems. Current research activities can be divided into three areas:

1. Shannon Theory: Properties of information measures; source and channel coding theory; analysis of communication systems with memory; modeling of real-world fading channels; effect of feedback on channel capacity and reliability function.

2. Joint Source-Channel Coding: Design, performance analysis and development of source coding (quantization) techniques and bandwidth-efficient channel coding schemes for noisy channels. Error analysis of communication systems.

3. Applications to Multimedia Communication: Reliable transmission of low bit-rate voice, image (JPEG) and video (MPEG) over land mobile radio or satellite channels; modeling and filtering of medical images with applications to Telemedicine.
