Abstract
According to the present disclosure, a method for tracking power levels of a wireless communications signal comprises receiving a feedback signal indicative of a power level of a wireless communication signal associated transmitted from a transmit path to an antenna of a wireless communication element. The method further comprises receiving a reference signal associated with a digital signal converted into the wireless communication signal. Additionally, the method comprises determining a gain of the feedback signal with respect to the reference signal and determining a gain error based on the determined gain and an expected gain.
Claims14
A wireless communication element comprising:
- a transmit path configured to convert a digital signal into a wireless communication signal;
- an antenna coupled to the transmit path and configured to transmit the wireless communication signal;
- a feedback receive path communicatively coupled between the antenna and transmit path and configured to receive a feedback signal indicative of a power level of the wireless communication signal transmitted from the transmit path to the antenna;
- and
- an error tracking path coupled to the feedback receive path, the error tracking path configured to:
- receive the feedback signal;
- compensate for a gain imbalance between an I channel component and a Q channel component of the feedback signal such that the gain of the I channel component and the gain of the Q channel component are approximately equal;
- compensate for a phase imbalance between the I channel component and the Q channel component of the feedback signal such that the I channel component and the Q channel component are in approximately quadrature phase with each other;
- receive a reference signal associated with the digital signal;
- determine a gain of the feedback signal with respect to the reference signal;
- determine a gain error based on the determined gain and an expected gain;
- and
- detect interference associated with the wireless communication signal based on an unexpected change in a magnitude of the feedback signal and a corresponding change in a difference between the feedback signal and the reference signal multiplied by the determined gain.
