The Mockingbird RF Learning Toolbox is an optional software toolbox that extends the built-in capabilities of the Mockingbird RF Test System. The RF Learning Toolbox provides the capability to learn the frequency and temporal characteristics of RF signals or the RF environment through direct observation. The resulting learned RF signatures can then be used to create an emulated waveform that has the same PSD shape and temporal characteristics or communications battle rhythm.

The RF Learning Toolbox isolates signals in the observed frequency spectrum and learns the Power Spectral Density (PSD) and probability distributions of the ON and OFF times for each signal. The combination of these three learned results (PSD, ON and OFF time distributions) is called a RF signature.

Each learning session is defined over a specific frequency band and learning time duration. The longer the learning session the more accurate the learned statistics, but we have had very good success for RF learning sessions from on the order of 15 min to 1 hour. The result of the RF learning session is a signal list that includes the RF signature for each signal.
