Abstract: Systems and methods are provided for receiver nonlinearity estimation and cancellation. Narrowband (NB) estimation may be performed in a receiver during handling of received radio frequency (RF) signals. The narrowband (NB) may include generating estimation channelization information relating to received RF signals; generating reference nonlinearity information relating to one or more other signals, which may cause or contribute to nonlinearity that affects the processing of the received RF signals; and generating, based on the estimation channelization information relating to the received RF signals and the reference nonlinearity information relating to the other signals, control data for configuring nonlinearity cancellation functions. The received RF signals may be channelized, and the estimation channelization information may be generated based on the channelization of the received RF signals.

Abstract: Systems and methods are provided for receiver nonlinearity estimation and cancellation. During processing of received radio frequency (RF) signals, it may be determined when one or more other signals, different from the received RF signals, cause nonlinearity affecting processing of the RF signals, and one or more cancellation adjustments may be applied during processing of the RF signals, for mitigating effects of the nonlinearity. Determining the one or more cancellation adjustments may be based on narrowband (NB) estimation of the effects of the nonlinearity, and the one or more cancellation adjustments may be configured as wideband (WB) corrections. The NB estimation may be applied based on channelization of the received RF signals. The NB estimation may comprise generating reference nonlinearity information relating to the one or more other signals, and generating, based on the reference nonlinearity information, control data for configuring the one or more cancellation adjustments.
