  8. ABCD • Points of Agreement for UWB signalling • Modulation scheme should admit multiple classes of receivers • Transmitter based on deterministic pulse structures • Should allow reception by coherent, differentially-coherent (can be TR) and non-coherent receivers • Provision for homogeneous operation when membership supports it • Ternary modulation • Specific modulation format TBD • Sub-banding: • Center of three bands is mandatory • Other two optional • Wider bandwidth (1.5 GHz+) concentric with center band is optional • CDMA within frequency bands • Harmonic chip rate – integer relationship between center frequency and chip rate • Consider ways to avoid Japanese UNII band (shift band lower) • Integer-plus-half is also proposed, some concerns with DC balance • Maintain 3.1 corner • Constant PRF is desired as possible • Specific band plan - TBD • Cost effective reference frequency with appropriate PPM • Specific frequency and tolerance is TBD • Potential for optional chirp mode (at best, if and where allowed)

  9. Specific Mandatory/Option Breakdown for UWB signalling • As noted on previous slide • Mandatory • ~500 center band • AM of 3.1-4.9 is 3.975 • GM of 3.1-4.9 is 3.877 • Center band frequency is TBD, but must be in [3.85 to 4.05] • Optional • 2 additional 500 MHz bands for FDM – center frequencies TBD • Wideband concentric with center specified above • Sub-GHz band • Chirp of some form (could be 2.4 GHz band – Merger E) • Chaotic waveform and SOP mechanisms for homogeneous (chaos-only) networks • Add TH as additional SOP mechanism • Add chirp specifically for UWB as SOP mechanism • Add specific optional band > 6 GHz with guaranteed >1.5GHz BW • Support mode for higher data rates (few to 10 Mbps) • Other issues • Desire to have common packet for communications and ranging if possible • Multiple (2-few) PRF in band

  10. UWB signalling is one of the two valid modes for communication • 2.4 GHz chirp is a valid mode for communication only • Ranging shall not be supported for 2.4 GHz chirping, and shall be supported for UWB signalling • UWB is valid for both communications and ranging
