The current research focus includes error control codes and applications of error control codes. Ongoing UG/PG/PhD projects are on Block and Convolutional Turbo codes, LDPC codes and BCH codes. Optimization techniques for decoding algorithms are also a focus of our research. Current research is also based on coded cryptographic scheme for reliable and secure communication. One of the future focuses of the group will be in the area of Genomic coding.
