  • Publication number: 20230318648
    Abstract: A system includes a receiver (RX) configured to receive an RX output signal in an RX band, where the RX output signal has a first passive intermodulation (PIM) source in the RX band and a second PIM source in the RX band; and a processing device configured to: receive the RX output signal from the receiver on an RX path, receive a crest factor reduction (CFR) output signal from a CFR on a transmit (TX) path, identify the first PIM source and the second PIM source based on the RX output signal and the CFR output signal, calibrate the CFR output signal based on the first and second PIM sources in 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.

  • Publication number: 20230318656
    Abstract: 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.
