Acquisition of direct-sequence ultra-wideband signals [PDF]
IEEE Wireless Communications and Networking Conference, 2005, 2005 Very high rate packet data systems, such as those based on ultra-wideband (UWB) signaling, face an increasingly important challenge - achieving fast timing acquisition and synchronization (which must be done typically on an individual packet basis) to minimize preamble overhead and optimize (packet) throughput.
