Abstract
An amplifier is provided for optimizing gain. The amplifier determines an optimal gain from inputs including the forward link and reverse link input power. The inputs are processed to determine an optimal gain of the amplifier. The optimal gain may be accessed from a lookup table that accounts for characteristics of the amplifier, the cell phone (or other device), and the base station (or base stations). The optimal gain is set to account at least for industry standards, amplifier oscillation issues, base station overload protection, and base station noise floor protection.
Claims32
A method for setting a gain of an amplifier operating in a network, the method comprising:
- measuring an input power to the amplifier;
- and
- comparing the input power to a threshold level;
- and
- setting the gain of the amplifier to a value in a lookup table when the input power exceeds the threshold level.
A method for calculating optimal gain in an amplifier, the method comprising:
- measuring a forward link input power and a reverse link input power of the amplifier;
- comparing the forward link input power to a first power overload protection threshold level when the forward link input power does not exceed a noise floor threshold level, wherein the gain is set to maximum gain when the forward link input power does not exceed the first power overload protection threshold level;
- and
- comparing the reverse link input power to a second power overload protection threshold level when the forward link input power exceeds the first power overload protection threshold level, wherein the gain is set to the maximum gain when the reverse link input power exceeds the second power overload protection threshold level and wherein the gain is set according to a value in a lookup table when the reverse link input power does not exceed the second power overload protection threshold level.
A method for setting a gain of an amplifier, the method comprising:
- sampling a forward link power input and a reverse link power input;
- performing, in any order:
- comparing the forward link power input to a first threshold and a second threshold to generate a first input and a second input;
- and
- comparing the reverse link power input to a third threshold to generate a third input;
- processing the first input, second input, and third input using one or more subroutines to produce one or more outputs;
- determining an optimal gain for the amplifier based on the one or more outputs of the one or more subroutines;
- and
- setting the gain of the amplifier to the optimal gain.
A method for setting a gain of an amplifier, the method comprising:
- sampling a first input and a second input to the amplifier;
- performing a plurality of comparisons between at least one of the first input and the second input and one or more thresholds;
- generating one or more outputs from the plurality of comparisons;
- and
- setting a gain of the amplifier based on the one or more outputs to protect at least one of base station noise floor or base station overload.
