Zusammenfassung:According to an aspect of an embodiment, a base station configured for enhanced receiver sensitivity may comprise a processing device and a receiver. The receiver (Rx) may be configured to receive an Rx output signal in an Rx band. The processing device may be configured to receive the Rx output signal from the receiver on an Rx path and receive a crest factor reduction (CFR) output signal from a CFR on a transmit (Tx) path. The processing device may be configured to calibrate the CFR output signal based on the Rx output signal to generate a non-linear actuation (NA) input signal and generate an intermodulation distortion signal by using an NA function on the NA input signal.
