PEAK DETECTION IN DATA STREAM

摘要

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.
