Abstract

Embodiments of the present invention include methods and systems for detecting a peak of an ultra-wide-band (UWB) signal in a data stream. The system (1100) for detecting a peak of an ultra-wide-band (UWB) signal (1120) in a data stream (102) includes: one or more processors (1001); and a non-transitory computer-readable medium or media (1002) comprising one or more sequences of instructions which, when executed by the one or more processors (1001), causes steps to be performed comprising: selecting a portion (104) of a data stream (102) in a current clock cycle, the portion (104) of the data stream includes a preset number of data samples; finding a set of data samples included in the preset number of data samples, the set of data samples includes one or more consecutive data samples and has a uniform magnitude; and promoting the set of data samples as a peak if the uniform magnitude is higher than a magnitude of a first data sample that immediately precedes the set of data samples and a magnitude of a second data sample that immediately follows the set of data samples.

First claim

What is claimed is:

1. A method for detecting a peak of a ultra-wide-band (UWB) signal in a data stream, comprising:
selecting a portion of the data stream in a first clock cycle, the portion of the data stream includes a plurality of data samples that are simultaneously taken in the first clock cycle;
finding a set of data samples included in the plurality of data samples, the set of data samples includes one or more consecutive data samples that have a uniform magnitude; and
promoting the set of data samples as a peak responsive to the uniform magnitude being higher than at least one of a magnitude of a first data sample taken during a second clock cycle and immediately preceding the set of data samples and a magnitude of a second data sample taken during a third clock cycle and immediately following the set of data samples.

2. A method as recited in claim 1 , further comprising:
when at least one data sample, that is taken in the third clock cycle and immediately follows the set of data samples, has a same magnitude as the uniform magnitude, promoting the set of data samples as the peak responsive to the uniform magnitude being larger than a magnitude of a data sample that immediately follows the at least one data sample.

3. A method as recited in claim 1 , further comprising:
when at least one data sample, which is taken in the third clock cycle and immediately follows the set of data samples, has a same magnitude as the uniform magnitude, promoting the set of data samples as the peak responsive to a time duration of the at least one data sample exceeding a preset time interval.

4. A method as recited in claim 1 , further comprising:
responsive to the promotion, not detecting a peak of the data stream during a time interval that is commensurate with the uniform magnitude.

5. A method as recited in claim 1 , further comprising:
ruling out the peak responsive to the uniform magnitude being below a preset threshold.

6. A system for detecting a peak of an ultra-wide-band (UWB) signal in a data stream, comprising:
one or more processors; and
a non-transitory computer-readable medium or media comprising one or more sequences of instructions which, when executed by the one or more processors, causes steps to be performed comprising:
selecting a portion of the data stream in a first clock cycle, the portion of the data stream includes a plurality of data samples that are simultaneously taken in the first clock cycle;
finding a set of data samples included in the plurality of data samples, the set of data samples includes one or more consecutive data samples that have a uniform magnitude; and
promoting the set of data samples as a peak responsive to the uniform magnitude being higher than at least one of a magnitude of a first data sample taken during a second clock cycle and immediately preceding the set of data samples and a magnitude of a second data sample taken during a third clock cycle and immediately following the set of data samples.

7. A system as recited in claim 6 , wherein the steps further comprise:
when at least one data sample, that is taken in the third clock cycle and immediately follows the set of data samples, has a same magnitude as the uniform magnitude, promoting the set of data samples as the peak responsive to the uniform magnitude being larger than a magnitude of a data sample that immediately follows the at least one data sample.

8. A system as recited in claim 6 , wherein the steps further comprise:
when at least one data sample, which is taken in the third clock cycle and immediately follows the set of data samples, has a same magnitude as the uniform magnitude, promoting the set of data samples as the peak responsive to a time duration of the at least one data sample exceeding a preset time interval.

9. A system as recited in claim 6 , wherein the steps further comprise:
responsive to the promotion, not detecting a peak of the data stream during a time interval that is commensurate with the uniform magnitude.

10. A system as recited in claim 6 , wherein the steps further comprise:
ruling out the peak responsive to the uniform magnitude being below a preset threshold.

11. A system as recited in claim 6 , further comprising:
multiple receivers that each receive a UWB signal; and
a device coupled to the multiple receivers, the device generates the data stream using the UWB signals sent by the multiple receivers.

12. A system as recited in claim 11 , further comprising:
a switch disposed between the multiple receivers and the device, the switch controls data flow from the multiple receivers to the device.
