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. The other signals may be channelized, and the reference nonlinearity information may be generated based on the channelization of the other 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.

Abstract translation: 为接收机非线性估计和消除提供了系统和方法。 在接收的射频（RF）信号的处理期间，可以确定与接收的RF信号不同的一个或多个其他信号是否导致影响RF信号的处理的非线性，并且可以在处理期间应用一个或多个取消调整 RF信号，用于减轻非线性的影响。 确定一个或多个取消调整可以基于对非线性的影响的窄带（NB）估计，并且一个或多个取消调整可以被配置为宽带（WB）校正。 可以基于所接收的RF信号的信道化来应用NB估计。 NB估计可以包括生成与一个或多个其他信号相关的参考非线性信息，并且基于参考非线性信息生成用于配置一个或多个取消调整的控制数据。
