Abstract

A system that incorporates aspects of the subject disclosure may perform operations including, for example, receiving, via an antenna, a signal generated by a communication device, detecting an interference in the signal, the interference generated by one or more transmitters unassociated with the communication device, and the interference determined from signal characteristics associated with a signaling protocol used by the one or more transmitters, and performing signal conditioning on the signal to reduce the interference. Other embodiments are disclosed.

Claims (52)

1. A device, comprising:

a processing system including a processor; and

a memory that stores executable instructions that, when executed by the device, facilitate performance of operations, the operations comprising:

receiving a signal over a mobile communication network resulting in a received signal, wherein the received signal comprises a desired signal and an interfering signal;

determining a profile of the received signal, wherein the profile comprises a time domain profile of the received signal;

determining a pre-determined time domain profile threshold based on signal characteristics of a desired signal without interference;

comparing the time domain profile of the received signal to the pre-determined time domain profile threshold based on a group of historical measurements;

determining that the time domain profile of the received signal exceeds the pre-determined time domain profile threshold; and

performing, responsive to the determining that the time domain profile of the received signal exceeds the pre-determined time domain profile threshold, signal conditioning on the received signal to mitigate the interfering signal.

2. The device of claim 1 , wherein the determining of the pre-determined time domain profile threshold comprises:

obtaining the group of historical measurements from the received signal; and

determining the pre-determined time domain profile threshold based on the group of historical measurements.

3. The device of claim 2 , wherein the group of historical measurements comprises a group of running averages of the received signal.

4. The device of claim 1 , wherein the performing of the signal conditioning on the received signal comprises performing signal conditioning on the received signal based on a time domain parameter.

5. The device of claim 1 , wherein the operations further comprise:

determining a time domain profile metric, wherein the pre-determined time domain profile threshold comprises a time domain profile metric threshold associated with the time domain profile metric.

6. The device of claim 5 , wherein the time domain profile comprises metric making measurements synchronized with timing of an air-interface.

7. The device of claim 5 , wherein the time domain profile comprises one or more of a mean of the received signal, a median of the received signal, a peak power of the received signal, an average of one or more of the mean, the median, or the peak power, or a ratio of one or more of the mean, the median, or the peak power.

8. The device of claim 1 , wherein the profile further comprises a frequency domain profile.

9. The device of claim 8 , wherein the performing of the signal conditioning on the received signal comprises performing signal conditioning on the received signal based on a frequency domain parameter.

10. The device of claim 8 , wherein the profile further comprises a frequency domain profile of the received signal the operations further comprise:

determining a pre-determined frequency domain profile threshold based on signal characteristics of a desired signal without interference;

comparing the frequency domain profile of the received signal to the pre-determined frequency domain profile threshold based on a group of historical measurements; and

determining that the frequency domain profile of the received signal exceeds the pre-determined time domain profile threshold determining a frequency domain metric, wherein the pre-determined frequency domain profile threshold comprises a frequency domain metric threshold associated with the frequency domain metric, wherein the performing signal conditioning on the received signal to mitigate the interfering signal is further responsive to the determining that the frequency domain profile of the received signal exceeds the pre-determined frequency domain profile threshold.

11. The device of claim 1 , wherein the group of historical measurements are obtained from the received signal.

12. A non-transitory, machine-readable storage medium, comprising executable instructions that, when executed by a circuit, facilitate performance of operations, comprising:

receiving a signal over a mobile communication network resulting in a received signal, wherein the received signal comprises a desired signal and an interfering signal;

determining a time domain profile of the received signal;

determining a pre-determined time domain profile threshold based on signal characteristics of a desired signal without interference;

comparing the time domain profile of the received signal to the pre-determined time domain profile threshold based on a group of historical measurements;

determining that the time domain profile of the received signal exceeds the pre-determined time domain profile threshold; and

performing signal conditioning on the received signal to mitigate the interfering signal.

13. The non-transitory, machine-readable storage medium of claim 12 , wherein the operations comprise determining the pre-determined time domain profile threshold.

14. The non-transitory, machine-readable storage medium of claim 13 , wherein the determining of the pre-determined time domain profile threshold comprises:

obtaining the group of historical measurements from the received signal; and

determining the pre-determined time domain profile threshold based on the group of historical measurements.

15. The non-transitory, machine-readable storage medium of claim 14 , wherein the group of historical measurements comprises a group of running averages of the received signal.

16. The non-transitory, machine-readable storage medium of claim 12 , wherein the determining of the pre-determined time domain profile threshold comprises:

obtaining the group of historical measurements from the received signal; and determining the pre-determined time domain profile threshold based on the group of historical measurements.

17. A method, comprising:

receiving, by a processing system including a processor, a signal over a mobile communication network resulting in a received signal, wherein the received signal comprises a desired signal and an interfering signal;

determining, by the processing system, a frequency domain profile of the received signal;

determining a pre-determined frequency domain profile threshold based on signal characteristics of a desired signal without interference;

comparing, by the processing system, the frequency domain profile of the received signal to the pre-determined frequency domain profile threshold based on a group of historical measurements;

determining, by the processing system, that the frequency domain profile of the received signal exceeds the pre-determined frequency domain profile threshold; and

performing, by the processing system and responsive to the determining that the frequency domain profile of the received signal exceeds the pre-determined frequency domain profile threshold, signal conditioning on the received signal to mitigate the interfering signal.

18. The method of claim 17 , wherein the determining of the pre-determined frequency domain profile threshold comprises:

obtaining, by the processing system, the group of historical measurements from the received signal; and

determining, by the processing system, the pre-determined frequency domain profile threshold based on the group of historical measurements.

19. The method of claim 17 , wherein the group of historical measurements comprises a group of running averages of the received signal.

20. The method of claim 17 , wherein the determining of the pre-determined frequency domain profile threshold comprises:

obtaining the group of historical measurements from the received signal; and determining the pre-determined frequency domain profile threshold based on the group of historical measurements.
