Research

Research Interests:

My research interests span the area of information theory and communications theory, more precisely, the area of sparse-graph codes, iterative belief-propagation decoding and network coding, and applications of related ideas in wireless multimedia delivery and next-generation wireless mobile cellular networks.

  • Codes on Graphs: LDPC Codes, Optimized Finite-Length Irregular LDPC Codes
  • Rateless Codes: Unequal Error Protection (UEP) Rateless Codes, Rateless Coding for Multimedia Streaming
  • Network Coding: Random Linear Network Coding (RLNC), UEP RLNC, RLNC for Multimedia Streaming
  • 5G Mobile Cellular Networks: machine type communications services in 5G (mMTC/URLLC), 5G radio access network design, 5G services for Smart Grid
  • Multimedia over Wireless: Multimedia delivery services over wireless cellular networks (LTE/LTE-A, 5G)
  • Multiple/Random Access: Random access using ALOHA-type protocols inspired by Codes on Graphs
  • Distributed Storage: Distributed Rateless Coding, Distributed Random Linear Coding, Storage Allocations
  • Probabilistic Graphical Models and Belief Propagation: factor graphs and BP in discrete (coding theory) and continuous (power grids) models
  • Compressed Sensing: Connections with sparse-graph codes, graphical models and Belief Propagation.
