Original Abstract Submitted
there is provided mechanisms for operating a dpd for a non-linear electronic device. a method is performed by a dpd controller. the method comprises receiving an input signal destined to be input to the non-linear electronic device. the method comprises selecting a basis function that represent non-linear input-output characteristics of the non-linear electronic device. the basis function is defined by kernels of a pruned volterra series, and comprises higher-than-order-1 polynomial terms, polynomial cross-terms, memory cross-terms, and common tap delays shared by all polynomial terms. the method comprises obtaining an output signal by subjecting the input signal to a linearization function defined by the basis function. the method comprises providing the output signal as input to the non-linear electronic device.
