Abstract

An integrated circuit comprises a main bus, one or more integrated processors, an external bus interface, memory, internal bus controller, a signal analyzer, timers, reset/clock generator, radio controller, optional data converters, and optional radio. The signal analyzer performs both time-domain and frequency-domain analysis of the input signal and supplies data to the one or more integrated processors for signal classification.

Claims

1. An integrated circuit, comprising:

a bus;

one or more integrated processors connected to the bus; and

a signal analyzer connected to the bus, the signal analyzer including a time-domain analyzer and a frequency-domain analyzer,

wherein the one or more integrated processors performs adaptive scanning based upon input provided by the signal analyzer.

2. The integrated circuit of claim 1, wherein the time-domain analyzer includes one or more programmable correlators to compare a signal input to the time-domain analyzer to one or more signal protocol patterns.

3. The integrated circuit of claim 1, wherein the one or more integrated processors control a scanning operation to locate a signal of interest, and once located, classify the located signal of interest.

4. The integrated circuit of claim 1, wherein the time-domain analyzer determines a first feature vector based at least in part on a signal input to the time-domain analyzer, the first feature vector including one or more of:

pulse width, pulse time of arrival, pulse repetition interval, received signal power, and correlation of the signal input to the time-domain analyzer with respect to one or more signal protocol patterns.

5. The integrated circuit of claim 1, wherein the frequency-domain analyzer determines a second feature vector based at least in part on a signal input to the frequency-domain analyzer, the second feature vector including one or more of:

max hold spectrum, decimated spectrum, peak magnitude level, peak magnitude frequency, and bandwidth.

6. The integrated circuit of claim 2, wherein control of the signal analyzer is based at least in part on output of the programmable correlators.

7. An integrated circuit, comprising:

a bus;

means for processing; and

means for performing signal analysis connected to the bus, the means for performing signal analysis including means for performing time-domain analysis and means for performing frequency-domain analysis,

wherein the means for processing performs adaptive scanning based upon input provided by the means for performing signal analysis.

8. The integrated circuit of claim 7, wherein the means for performing time-domain analysis includes correlation means to compare a signal input to the means for performing time-domain analysis to one or more signal protocol patterns.

9. The integrated circuit of claim 7, wherein the means for processing control a scanning operation to locate a signal of interest, and once located, classify the located signal of interest.

10. The integrated circuit of claim 7, wherein the means for performing time-domain analysis determines a first feature vector based at least in part on a signal input to the means for performing time-domain analysis, the first feature vector including one or more of:

pulse width, pulse time of arrival, pulse repetition interval, received signal power, and correlation of the signal input to means for performing time-domain analysis with respect to one or more signal protocol patterns.

11. The integrated circuit of claim 7, wherein the means for performing frequency-domain analysis determines a second feature vector based at least in part on a signal input to the means for performing frequency-domain analysis, the second feature vector including one or more of:

max hold spectrum, decimated spectrum, peak magnitude level, peak magnitude frequency, and bandwidth.

12. The integrated circuit of claim 8, wherein control of the means for performing signal analysis is based at least in part on output of the correlation means.
