Abstract
A method of beamforming is provided. A single non-linear equalization (NLEQ) coefficient set is generated in beamspace, the single NLEQ coefficient set configured to characterize non-linear behavior of a system having an array of N elements. M parallel digital signals are received, for transmission by N channels, respectively, the N channels corresponding to the N elements. Each of the M respective parallel digital signals are equalized, using an NLEQ filter based on the single NLEQ coefficient set, wherein the single NLEQ coefficient set is used for each of the N elements and wherein the equalizing is configured to generate a set of M linearized parallel digital signals. Using a single summer, the M linearized parallel digital signals are summed, to produce one or more beamspace channelized output signals.
