ABSTRACT:
The invention provides an automatic gain control and antenna selection method used in a receiver of a radio communication system. The received signal power is estimated by digital signal processing after analog-to-digital conversion in the system, in order to adjust the gain of the front end analog signal until the magnitude of the analog signal is adjusted to an optimum range of the digital signal processing. In addition, the ADC is utilized to estimate the signal power as the basis of the antenna selection.
