Iterative Synchronization of Multiuser Ultra-Wideband Signals
IEEE Transactions on Wireless Communications, 2010 In this paper, two novel iterative chip-level synchronization methods, one blind and the other data-aided, are proposed for chip-interleaved time-hopping (TH) ultra-wideband signals that are subject to intersymbol interference (ISI) and multiple access interference (MAI).
