Abstract
A method of controlling a signal power of a received signal received by a wireless communication device, the method including: measuring the signal power of the received signal at a plurality of time points in response to a gain control signal; calculating a variance of the signal power of the received signal at at least some time points of the plurality of time points; and controlling the signal power of the received signal based on a gain level determined according to the variance of the signal power of the received signal.

A method of controlling a signal power of a received signal received by a wireless communication device, the method comprising:
- measuring the signal power of the received signal at a plurality of time points in response to a gain control signal;
- calculating a variance of the signal power of the received signal at at least some time points of the plurality of time points;
- and
- controlling the signal power of the received signal based on a gain level determined according to the variance of the signal power of the received signal.
A communication processor, comprising:
- a power measuring module configured to measure signal power of a received signal at a plurality of time points in response to a gain control signal;
- a calculating module configured to calculate a variance of the signal power of the received signal at at least some time points of the plurality of time points;
- and
- a gain determining module configured to provide, to a variable gain amplifier, a gain level at which the signal power of the received signal is controlled according to the variance of the signal power of the received signal.
A wireless communication device, comprising:
- a receiving module configured to receive a gain control signal and a received signal;
- a communication processor configured to output a gain level determined according to a variance of a signal power of the received signal in response to the gain control signal;
- and
- a variable gain amplifier configured to control the signal power of the received signal based on the gain level,
- wherein the communication processor is configured to measure the signal power of the received signal at a plurality of time points, and to calculate the variance of the signal power of the received signal at at least some time points of the plurality of time points.
