Eigensequences for Multiuser Communication over the Real Adder Channel
arXiv:1502.03400 · doi:10.1109/ITS.2006.4433415
Abstract
Shape-invariant signals under the Discrete Fourier Transform are investigated, leading to a class of eigenfunctions for the unitary discrete Fourier operator. Such invariant sequences (eigensequences) are suggested as user signatures over the real adder channel (t-RAC) and a multiuser communication system over the t-RAC is presented.
