Ultra WideBand



Objectives 


Compared to traditional carrier-based, Ultra-Wide Band (UWB), or carrier-less, systems implement new paradigms in terms of signal generation and reception. Thus, designing an UWB communication system requires the understanding of how excess bandwidth and very low transmitted powers can be used jointly to provide a reliable radio link. This lecture is to provide the understanding the followings :


  • Large bandwidth enables very fine time-space resolution for accurate location of the UWB nodes and for distributing network time stamps.
  • Very short pulses are effectively counter-fighting the channel effect in very dense multipath environments.
  • Data rate (number of pulses transmitted per bit) can be traded with power emission control and distance coverage.
  • Very low power density leads to low probability of signal detection and adds security for all the layers of the communication stack.
  • Very low power density is obtained through radio regulation emission masks; UWB systems are suitable for coexistence with already deployed narrow-band systems.
