Abstract

Claims (17)

1 . A system for spectrum management, comprising:

a radiofrequency (RF) receiver, a signal processor, and a database connected to the signal processor;

wherein the RF receiver is operable to measure RF energy and output RF energy measurements to the signal processor;

wherein the signal processor is operable to:

generate signal data based on the RF energy measurements received from the RF receiver;

compare the generated signal data with at least one signal parameter stored in the database to identify at least one signal, the at least one signal parameter including hardware parameters;

determine if the at least one signal is moving using a frequency-locked loop by determining if there is a Doppler change in the at least one signal;

provide signal optimization parameters for signal optimization of the at least one signal based on measured terrain data stored in the database;

create a channel plan based on user input, external databases, or feature extraction from an RF environment using a Temporal Feature Extraction (TFE) function;

produce a settled percent using the TFE function based on the RF environment; and

determine that the at least one signal violates the channel plan;

wherein the identification of the at least one signal includes signal detection based on a calibration vector, a gradient detection algorithm, a first smoothing filter, a second smoothing filter;

wherein the second smoothing filter is performed only on frequencies outside a frequency range of the at least one signal;

wherein the hardware parameters include antenna position, antenna type, orientation, azimuth, gain, and/or equivalent isotropically radiated power (EIRP) for a transmitter associated with the at least one signal; and

wherein the at least one signal parameter stored in the database includes noise figure parameters.

2 . The system of claim 1 , wherein the signal processor is operable to determine environment parameters, wherein the environment parameters are based on a delta correction factor table stored in the database and a provided precipitation rate.

3 . The system of claim 1 , wherein the signal processor is operable to determine a spectral density, a center frequency, a bandwidth, a baud rate, a modulation type, a protocol, and a carrier using licensed spectrum of the at least one signal using information stored in the database.
