SYSTEMS, METHODS, AND DEVICES FOR AUTOMATIC SIGNAL DETECTION WITH TEMPORAL FEATURE EXTRACTION WITHIN A SPECTRUM
First Claim
1. A method for automatic signal detection in a radio-frequency (RF) environment, comprising:
- learning the RF environment in a predetermined period based on statistical learning techniques, thereby creating learning data;
forming a knowledge map based on the learning data;
automatically extracting at least one temporal feature of the RF environment from the knowledge map;
scrubbing a real-time spectral sweep against the knowledge map; and
detecting at least one signal in the RF environment.

Abstract
Systems, methods and apparatus for automatic signal detection with temporal feature extraction in an RF environment are disclosed. An apparatus learns the RF environment in a predetermined period based on statistical learning techniques, thereby creating learning data. A knowledge map is formed based on the learning data. The apparatus automatically extracts temporal features of the RF environment from the knowledge map. A real-time spectral sweep is scrubbed against the knowledge map. The apparatus is operable to detect a signal in the RF environment, which has a low power level or is a narrowband signal buried in a wideband signal, and which cannot be identified otherwise.
