Abstract
Devices and methods enable optimizing a signal of interest based on identifying and analyzing the signal of interest based on radio frequency energy measurements. Signal data is compared with stored data to identify the signal of interest. Signal degradation data is calculated based on noise figure parameters, hardware parameters and environment parameters. The signal of interest is optimized based on the signal degradation data. Terrain data may also be used for optimizing the signal of interest.

A method for automatic signal detection in a radio-frequency (RF) environment, comprising:
- learning the RF environment in a learning period based on statistical learning techniques, thereby creating learning data including power level measurements of the RF environment;
- forming a knowledge map based on the power level measurements of the RF environment;
- creating a channel plan based on the knowledge map, user input, and/or external databases;
- scrubbing a real-time spectral sweep against the knowledge map;
- calculating a first derivative of the power level measurements and a second derivative of the power level measurements;
- selecting most prominent derivatives of the first derivative and the second derivative;
- performing a squaring function on the most prominent derivatives;
- detecting at least one signal in the RF environment based on matched positive and negative gradients;
- averaging the real-time spectral sweep, removing areas identified by the matched positive and negative gradients, and connecting points between removed areas to determine a baseline;
- smoothing the real-time spectral sweep with a correction vector, wherein the correction vector is determined according to the real-time spectral sweep;
- subtracting the baseline from the real-time spectral sweep to reveal the at least one signal;
- and
- determining that one or more of the at least one signal violates the channel plan.
