Abstract
A signal detecting apparatus detects a signal received based on a current received and includes a detecting unit that detects, in the current received, a peak equal to or higher than a threshold and a time counting unit that counts a given period of time from a point in time of detection of the peak by the detecting unit. The signal detecting apparatus further includes a determining unit that determines whether the detecting unit has detected the peak again within the given period of time counted by the time counting unit. An output unit of the signal detecting apparatus outputs information indicating detection of the signal received when the determining unit determines that the peak has been detected again.
Claims7
A signal detecting apparatus that detects a signal received based on a current received, comprising:
- a detecting unit that detects, in the current received, a peak equal to or higher than a threshold;
- a time counting unit that counts a given period of time from a point in time of detection of the peak by the detecting unit;
- a determining unit that determines whether the detecting unit has detected the peak again within the given period of time counted by the time counting unit;
- and
- an output unit that outputs information indicating detection of the signal received when the determining unit determines that the peak has been detected again.
A signal receiving apparatus comprising:
- a signal detecting apparatus that detects a signal received based on a current received and includes:
- a detecting unit that detects, in the current received, a peak equal to or higher than a threshold,
- a time counting unit that counts a given period of time from a point in time of detection of the peak by the detecting unit,
- a determining unit that determines whether the detecting unit has detected the peak again within the given period of time counted by the time counting unit, and
- an output unit that outputs information indicating detection of the signal received when the determining unit determines that the peak has been detected again;
- a receiving unit that recovers data based on the current received;
- and
- a masking unit that outputs data recovered by the receiving unit when the output unit outputs information indicating detection of the signal received, the masking unit masking output from the receiving unit when the output unit does not output the information.
A signal detecting method of detecting a signal received based on a current received and comprising:
- detecting, in the current received, a peak equal to or higher than a threshold;
- counting a given period of time from a point in time of detection of the peak at the detecting;
- determining whether the detecting unit has detected the peak again within the given period of time counted at the counting;
- and
- outputting information indicating detection of the signal received when, at the determining, the peak has been determined to have been detected again.
