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 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.
Claims18
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 least some time points of the plurality of time points, wherein the calculating of the variance of the signal power of the received signal includes calculating the variance of the signal power of the received signal at an object time point based on a difference between the signal power of the received signal at the object time point and the signal power of the received signal at a time point prior to the object time point;
- storing the variance of the signal power of the received signal;
- and
- controlling the signal power of the received signal to have a first gain level when the number of frequency resources is less than or equal to a first number;
- and
- controlling the signal power of the received signal to have a second gain level, which is greater than the first gain level, when the number of frequency resources is greater than the first number and less than or equal to a second number, which is greater than the first number.
