PROBLEM TO BE SOLVED: To provide a receiver with improved linearity and noise figure, and reduced power consumption.SOLUTION: A receiver 400 includes a jammer detector 420 configured to detect the presence or absence of jamming in a communication signal within a gain state. The receiver further includes an amplifier 406 configured to amplify the communication signal in a high linearity receiving mode or a low linearity receiving mode, where the high linearity receiving mode corresponds with a lower gain for the gain state in the amplifier than the gain of the low linearity receiving mode. In addition, the receiver includes a processing unit 422 coupled to the jammer detector, the processing unit being configured to control the amplifier to amplify the communication signal in either the high linearity receiving mode or the low linearity receiving mode, based on the output of the jammer detector detecting the presence or absence of jamming in the communication signal. A method is also provided for processing a communication signal in a receiver. |
