Assignee: DIGITAL GLOBAL SYSTEMS, INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An apparatus for spectrum data management for a radio frequency (RF) environment, comprising:
at least one receiver, an automatic signal detection (ASD) module, and a learning and conflict detection engine;
wherein the apparatus is operable to sweep and learn the RF environment, thereby creating learning data including power level measurements of the RF environment;
wherein the apparatus is operable to form a knowledge map based on the power level measurements of the RF environment;
wherein the apparatus is operable to scrub a real-time spectral sweep against the knowledge map;
wherein the apparatus is operable to detect at least one signal in the RF environment based on matched positive and negative gradients;
wherein the apparatus is operable to average the real-time spectral sweep, remove areas identified by the matched positive and negative gradients, and connect points between removed areas to determine a baseline;
wherein the apparatus is operable to smooth the real-time spectral sweep with a correction vector, wherein the correction vector is determined according to the real-time spectral sweep;
wherein the apparatus is operable to use gradients from smoothed signal data to create a calibration vector;
wherein the apparatus is operable to use the calibration vector to de-bias raw signal data; and
wherein the apparatus is operable to subtract the baseline from the real-time spectral sweep to reveal the at least one signal.
