Abstract:
1. A method for performing an automatic gain control (AGC) and an antenna selection in a receiver of a radio communication system, the method comprising the steps of: receiving an analog receiving signal by one of a first antenna and a second antenna of the receiver; amplifying the analog receiving signal by an amplification unit with a gain; converting the analog receiving signal into a digital receiving signal by an N-bit analog-to-digital converter (ADC); comparing the digital receiving signal with a saturation threshold value; decreasing the gain of the amplification unit by an adjusting value if the digital receiving signal is larger than or equal to the saturation threshold value; and selecting one of the first and the second antenna to receive the analog receiving signal if the digital receiving signal is smaller than the saturation threshold value, wherein the saturation threshold value corresponds to N.
