proposal main features
Proposal Main Features
  • Impulse-radio based (pulse-shape independent)
  • Support for different receiver architectures (coherent/non-coherent)
  • Flexible modulation format
  • Support for multiple rates
  • Enables accurate ranging/positioning
  • Support for multiple SOP
motivation for 2 4
Motivation for (2-4):
  • Supports homogenous and heterogeneous network architectures
  • Different classes of nodes, with different reliability requirements (and cost) must inter-work
uwb technology
UWB Technology
  • Impulse-Radio (IR) based:
    • Very short pulses  Reduced ISI
    • Robustness against fading
    • Episodic transmission (for LDR) allowing long sleep-mode periods and energy saving
  • Low-complexity implementation
modulation features
Modulation Features
  • Simple, scalable modulation format
  • Flexibility for system designer
  • Modulation compatible with multiple coherent/non-coherent receiver schemes
  • Time hopping (TH) to achieve multiple access
commonalities with other proposals
Commonalities with Other Proposals
  • The present document is the result of preliminary merging efforts among the new CWC/STm/LETI/AetherWire/MERL/Harris/FTR&D/TDC group. Work is still ongoing for refining and consolidation of some of the parameters described in this proposal.
  • Discussions are under way for further collaborations and merging in 802.15.4a.

Definitions

Coherent RX: The phase of the received carrier waveform is known, and utilized for demodulation

Differentially-coherent RX: The carrier phase of the previous signaling interval is used as phase reference for demodulation

Non-coherent RX: The phase information (e.g. pulse polarity) is unknown at the receiver

-operates as an energy collector

-or as an amplitude detector
