Abstract
A method can include: generating a first compensation value based on a receiving frequency, where the first compensation value represents attenuations of a wireless signal at different receiving frequencies during transmission to an analog receiving circuit; generating a second compensation value based on an automatic gain control coefficient, where the second compensation value represents gain errors corresponding to different automatic gain control coefficients; and generating a received signal strength indication based on the first and second compensation values, an intermediate frequency signal strength, and a gain of the intermediate frequency signal with respect to a received signal.
