Abstract
Technology for a repeater is disclosed. The repeater can include one or more amplification and filtering signal paths. The repeater can include a controller. The controller can detect an oscillation in the repeater. The controller can reduce a gain in the repeater by a first amount to cease the oscillation in the repeater. The controller can reduce the gain in the repeater further by a second amount to create an oscillation margin. The controller can modify the gain in the repeater further by a third amount to create an offset to the oscillation margin.
Claims22
A repeater, comprising:
- one or more amplification and filtering signal paths;
- and
- a controller configured to:
- detect an oscillation in the repeater;
- reduce a gain in the repeater by a first amount to cease the oscillation in the repeater;
- reduce the gain in the repeater further by a second amount to create an oscillation margin level;
- modify the gain in the repeater further by a third amount to create an offset to the oscillation margin level, wherein the offset to the oscillation margin level is an oscillation margin offset level that is less than the oscillation margin level;
- and
- increase a gain of the repeater by the oscillation margin offset level to verify an accuracy of the oscillation margin level, wherein the oscillation margin offset level reduces a noise floor impact of the repeater when the gain is increased to verify the accuracy of the oscillation margin level.
A signal booster, comprising:
- one or more amplification and filtering signal paths;
- and
- a controller configured to:
- reduce a gain in the signal booster by a first amount to create an oscillation margin level;
- reduce the gain in the signal booster further by a second amount to create an additional margin to the oscillation margin level, wherein the additional margin to the oscillation margin level is an oscillation margin offset level that is less than the oscillation margin level;
- and
- increase a gain of the signal booster by the oscillation margin offset level to verify an accuracy of the oscillation margin level, wherein the oscillation margin offset level reduces a transmitted noise power from the repeater when the gain is increased to verify the accuracy of the oscillation margin level.
At least one non-transitory machine readable storage medium having instructions embodied thereon for reducing oscillation in a signal booster, the instructions when executed by one or more processors perform the following:
- determining an oscillation amplification threshold level at which oscillation is reduced or ceases to occur at the signal booster;
- selecting an oscillation margin level;
- operating the signal booster at an amplification level that is the oscillation margin level below the oscillation amplification threshold level;
- selecting an oscillation margin offset level that is less than the oscillation margin level;
- increasing a gain of the signal booster by the oscillation margin offset level to periodically determine if an oscillation occurs at the signal booster while operating at the increased gain level, wherein the oscillation margin offset level for the increased gain reduces a noise floor impact of the signal booster;
- and
- decreasing the gain of the signal booster by the oscillation margin offset level to operate the signal booster at the amplification level.
