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 a data stream in a first clock cycle, the portion 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.

2 . A method as recited in claim 1 , wherein the first and second data samples are included in the selected portion of the data stream.

3 . A method as recited in claim 1 , wherein the second data sample is included in the selected portion of the data stream, the first data sample is included in a first portion of the data stream, and the first portion of the data stream is taken in a second clock cycle that immediately precedes the first clock cycle.

4 . A method as recited in claim 1 , wherein the first data sample is included in the selected portion of the data stream, the second data sample is included in a second portion of the data stream, and the second portion of the data stream is taken in a third clock cycle that immediately follows the first clock cycle.

5 . A method as recited in claim 4 , further comprising:
when at least one data sample, that is included in the second portion of the data stream 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 if the uniform magnitude is larger than a magnitude of a data sample that immediately follows the at least one data sample.

6 . A method as recited in claim 4 , further comprising:
when at least one data sample, which is included in the second portion of the data stream 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 if a time duration of the at least one data sample exceeds a preset time interval.

7 . 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.

8 . A method as recited in claim 1 , further comprising:
ruling out the peak if the uniform magnitude is below a preset threshold.

9 . A method as recited in claim 1 , wherein the peak corresponds to a UWB signal.

10 . 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 a data stream in a first clock cycle, the portion 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.

11 . A system as recited in claim 10 , wherein the first and second data samples are included in the selected portion of the data stream.

12 . A system as recited in claim 10 , wherein the second data sample is included in the selected portion of the data stream, the first data sample is included in a first portion of the data stream, and the first portion of the data stream is taken in a second clock cycle that immediately precedes the first clock cycle.

13 . A system as recited in claim 10 , wherein the first data sample is included in the selected portion of the data stream, the second data sample is included in a second portion of the data stream, and the second portion of the data stream is taken in a third clock cycle that immediately follows the first clock cycle.

14 . A system as recited in claim 13 , wherein the steps further comprise:
when at least one data sample, that is included in the second portion of the data stream 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 if the uniform magnitude is larger than a magnitude of a data sample that immediately follows the at least one data sample.

15 . A system as recited in claim 13 , wherein the steps further comprise:
when at least one data sample, which is included in the second portion of the data stream 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 if a time duration of the at least one data sample exceeds a preset time interval.

16 . A system as recited in claim 10 , 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.

17 . A system as recited in claim 10 , wherein the steps further comprise:
ruling out the peak if the uniform magnitude is below a preset threshold.

18 . A system as recited in claim 10 , wherein the peak corresponds to a UWB signal.

19 . A system as recited in claim 10 , 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.

20 . A system as recited in claim 19 , further comprising:
a switching module disposed between the multiple receivers and the device, the switching module controls data flow from the multiple receivers to the device.
