Speech Title: Robust Remaindering for Real Numbers and Its Applications in Mod Sampling


Abstract: A large integer can be reconstructed from its several much smaller remainders and Chinese Remainder Theorem (CRT) provides a solution. However, it is well-known that CRT is not robust in the sense that a small error in a remainder may cause a large error in the reconstruction. We have studied robust CRT in the last decade such that a large integer can be robustly reconstructed from its erroneous remainders as long as the errors in the remainders are not too large. In this talk, I will briefly talk about the robust CRT not only for large integer reconstructions but also for large real number reconstructions from erroneous remainders. We then briefly introduce its applications in mod sampling, where a signal is reconstructed from its mod samplings. It is related to unlimited sampling.
