Residue Number System Assisted Fast Frequency-Hopped Synchronous Ultra-Wideband Spread-Spectrum Multiple-Access: A Design Alternative to Impulse Radio

open access: yes, 2002
Ultra-wideband (UWB) systems having a bandwidth on the order of gigahertz have recently received wide attention both in the U.S. and in Europe. The family of UWB systems may communicate either by generating ultra-wideband signals or with the aid of ...

Low-Complexity Erasure Insertion in Frequency-Hopping Spread-Spectrum Communications Subjected to Fading and Partial-Band Interference

open access: yes, 2001
In this paper we propose two novel low-complexity, low-delay erasure insertion schemes, namely the Output Threshold Test (OTT) and joint Maximum Output and Ratio Threshold Test (MO-RTT).
