Abstract
Exemplary embodiments are disclosed of methods and systems of power detection in RF circuits to provide gain compensation for vehicle systems. In exemplary embodiments, a module (e.g., a front end module (FEM), compensor, compensator, etc.) includes a gain modifier, a power detector, and a controller. The power detector is configured to detect a power output of the gain modifier. The controller is configured to determine a mean of n samples taken by the power detector. The controller is also configured to determine a boundary to mean ratio of the n samples. The controller is further configured to adjust a detected value of the power detector based on the mean and the boundary to mean ratio.
Claims25
A module comprising:
- a gain modifier;
- a power detector configured to detect a power output of the gain modifier;
- and a controller configured to:
- determine, from n samples from the power detector, a mean of the n samples taken by the power detector;
- determine, from the n samples from the power detector, a maximum peak of the n samples taken by the power detector;
- determine, from the n samples from the power detector, a minimum peak of the n samples taken by the power detector;
- determine, based on at least one characteristic of a modulated signal, a boundary to mean ratio of the n samples, wherein the boundary is determined using the maximum peak or the minimum peak, and the at least one characteristic of the modulated signal;
- adjust a detected value of the power detector based on the mean and the boundary to mean ratio;
- and
- control gain of the gain modifier based on the adjusted detected value.
