Abstract

The present invention provides systems and methods relating to ultra-wide band communications. A method is provided for transmitting information using ultra-wide band transmission. The method includes allocating, for signal transmission, each of a plurality of frequency sub-bands. The method further includes sending an ultra-wide band transmission comprising the information by transmitting a burst symbol cycle signal over each of the plurality of frequency sub-bands.

Claims (11)

1. A method for transmitting information using ultra-wide band transmission, the method comprising:

allocating, for signal transmission, each of a plurality of frequency sub-bands; sending an ultra-wide band transmission comprising the information by transmitting a burst symbol cycle signal over each of the plurality of frequency sub-bands; switching off power to at least one circuit during OFF periods of a transmission to decrease power consumption; and maintaining signal frequency and phase from an end of an ON period to a beginning of the following ON period.

2. The method of claim 1 , comprising sending at least two of the burst symbol cycle signals serially.

3. The method of claim 1 , comprising utilizing at least one of an analog wave generator, digital wave generator, and a combination analog and digital wave generator.

4. A method for transmitting information using ultra-wide band transmission, the method comprising: allocating, for signal transmission, each of a plurality of frequency sub-bands; and sending an ultra-wide band transmission comprising the information by transmitting a signal over each of the plurality of frequency sub-bands; wherein phase continuity is maintained by: dividing each of the frequency sub-bands into a plurality of segments; and cycling transmission between segments of each of the sub-bands; wherein the method comprises: switching off power to at least one circuit during OFF periods of a transmission to decrease power consumption; and maintaining signal frequency and phase from an end of an ON period to a beginning of the following ON period.

5. A method for transmitting information using ultra-wide band transmission, the method comprising: allocating, for signal transmission, each of a plurality of frequency sub-bands; and sending an ultra-wide band transmission comprising the information by transmitting a signal over each of the plurality of frequency sub-bands, comprising producing at least one analog carrier wave of a frequency sub-band using outputs from a plurality of digital to analog converters; wherein the method comprises: switching off power to at least one circuit during OFF periods of a transmission to decrease power consumption; and maintaining signal frequency and phase from an end of an ON period to a beginning of the following ON period.

6. The method of claim 5 , wherein producing the at least one analog carrier wave comprises each of the digital to analog converters outputting a portion of the analog carrier wave based on an input bit, and comprises cycling through input values to produce consecutive segments of the analog carrier wave.

7. A method for transmitting information using ultra-wide band transmission, the method comprising: allocating, for signal transmission, each of a plurality of frequency sub-bands; and sending an ultra-wide band transmission comprising the information by transmitting a signal over each of the plurality of frequency sub-bands, comprising using a sine wave envelope to reduce side lobes in at least one carrier frequency, comprising multiplying a carrier signal by a sine wave of a lower frequency than the carrier frequency.

8. The method of claim 7 , comprising varying pulse bandwidth while pulse repetition frequency remains constant, to facilitate control of signal spectrum characteristics and receiver selectivity.

9. The method according to claim 7 , wherein the method comprises switching off power to at least one circuit during OFF periods of a transmission to decrease power consumption; and maintaining signal frequency and phase from an end of an ON period to a beginning of the following ON period.

10. The method according to claim 7 , wherein the method comprises utilizing a sine wave rectifier having an adjustable threshold.
