Abstract
Systems and methods are provided for adjusting a noise figure in a radio receiver. An example method includes receiving a radio frequency (RF) signal at a RF receiver section. The RF receiver section includes at least one RF receiver element. The RF receiver element is controllable by at least one tuning variable. The RF signal is processed to generate a processed analog signal, which is converted to a digital signal. The digital signal is used to determine a performance parameter. The at least one tuning variable of the at least one RF receiver element is controlled to adjust the noise figure based on the performance parameter. In another aspect of the invention, an example radio receiver is provided. The radio receiver includes a RF receiver section having at least one RF receiver element. A controller determines a performance parameter using the digital signal and controls the at least one tuning variable to adjust the noise figure based on the performance parameter.
