Method and Apparatus for Sparse Polynomial Equalization of RF Receive Chains

A radio frequency (RF) receiver includes an analog receiver chain followed by digital circuitry for reducing nonlinear distortion components within an output signal of the analog receiver chain. In at least one embodiment, the digital circuitry includes a digital equalizer that is configured with a sparse set of Volterra series coefficients. In this manner, a desired level of linearity performance may be achieved in the receiver with relatively low power consumption.
