Patent ID: 7764725

Claim:
A method for transmitting data using ultra-wideband techniques, said method comprising the steps of: (a) providing a transmitter subsystem configured to perform the steps of— (a.1) providing a UWB channel as a series of UWB signal pulses, (a.2) dividing the UWB channel into N bands, (a.3) transmitting each pulse of said series through a band of said N divided bands, and (a.4) modulating said series of UWB pulses by selectively using at least one modulation technique from the group consisting of time/phase, frequency, and amplitude, said selection being based on sub-band channel conditions; and (b) providing a receiver subsystem configured to perform the steps of— (b.1) receiving a UWB signal divided into N bands, (b.2) combining the N bands into a UWB channel, and (b.3) deriving a series of UWB pulses from the combined N bands.
