Asst. Professor Dolecek on a Collaborative NSF Grant

Assistant Professor Lara Dolecek is PI on a three-year collaborative grant entitled, Spatially Coupled Sparse Codes on Graphs - Theory, Practice, and Extensions. The project receives over $750K in funding from NSF to investigate a new approach to protecting the reliability of digital communication and digital storage systems using a novel graphical concept called "spatial coupling". The spatial coupling formulates the "encoding" and "decoding" of data in terms of a novel graphical representation; this formulation has several advantages over existing techniques for insuring data integrity, including better performance at very low power and the absence of an 'error floor'. This research will be performed in collaboration with the University of Notre Dame, New Mexico State and San Diego State University.
