Title: Integer Signal Recovery: Theory, Algorithms and Applications

报告摘要:In many applications, such as wireless communications, signal processing and GPS, we need to recover an integer parameter vector from an integer linear model. In this talk, we will first theoretically show that some commonly used lattice reductions, which are preprocess tools for recovering integer vectors, can always improve the success probability of some commonly used suboptimal recovery algorithms, and then show that they can decrease the complexity of the optimal method for detecting integer vectors. Finally, we will propose a polynomial time algorithm to solve a special class of shortest vector problem arising in communications.
