Abstract :
Emerging technologies including wireless multimedia and personal area networks (WPANs) call for high-rate systems capable of supporting multiple users (piconets) with variable rates. These requirements motivate multi-band ultra-wideband (UWB) radios with low-cost, short time-to-market transceivers. Relative to baseband UWB radios, multi-band systems offer certain advantages, but special multiple access (MA) schemes are needed. To this end, we introduce a cross-band flexible UWB MA scheme for multi-piconet WPANs. The resultant so termed FLEX-UWB design offers resilience against multi-user interference (MUI), can accommodate various spreading alternatives, enables full multipath diversity, and can affect scalable spectral efficiency (from low, to medium and high data rates).
