Spectrum Monitoring

Capture and analyze IQ data from the air using preamble or energy detection

Configure your software-defined radio (SDR) as a preamble detector or energy detector to detect and capture specific signals from the air. You can specify standard-based or custom waveforms for detection. Use the captured data to analyze, simulate, test, and validate wireless systems.

Objects

`preambleDetector`	Configure SDR as preamble detector (Since R2022a)
`energyDetector`	Configure SDR as energy detector (Since R2023b)

Functions

`capture`	Capture signal of interest from the air upon detection (Since R2022a)
`plotThreshold`	Plot preamble detection signals for triggering (Since R2022a)
`plotDetectionSignals`	Plot energy detection signals for triggering (Since R2023b)
`transmit`	Transmit waveform using preamble or energy detector (Since R2022a)
`stopTransmission`	Stop transmission from preamble or energy detector (Since R2022a)
