Talk Title: Sensing Compressed Signal, Codes on Graphs and Reliability of Memories
Abstract: Almost all areas of Electrical Engineering are rich sources of problems concerned with discrete mathematical structures. In this talk, we describe an array of such problems dealing with issues of communication, signal processing and storage. To highlight the methods being used, we describe in more detail our work on codes for flash memory and the rank modulation scheme. We reduce this problem to a set of combinatorial questions for the Kendall tau metric space defined on the set of permutations of n elements.
Our results are related to the areas of error-correcting codes (codes on graphs, constrained codes and codes for high-density magnetic recording), data reliability (flash memories), and compressed sensing. We also point out that similar combinatorial and probabilistic methods offer promise in such areas as group testing in Biology and data security.
