Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus may receive an indication of a selected digital pre-distortion (DPD) kernel from multiple DPD kernels. The apparatus may store multiple envelope values associated of with samples of an in-phase/quadrature (I/Q) signal and select a subset of envelope values based at least in part on the selected DPD kernel. The apparatus may generate, using the subset of envelope values and a look-up-table (LUT) component, an envelope computation value. The apparatus may store multiple computational values associated with the samples and select, based at least in part on the selected DPD kernel, at least one subset of computational values. The apparatus may generate an output sample that includes DPD based at least in part on combining the envelope computation value with the at least one subset of computational values. Numerous other aspects are described.
