Abstract
A method for determining a plurality of digital pre-distortion, DPD, models. The method comprising obtaining test data indicating a set of test cases. The method further comprising dividing the set of test cases into subsets of test cases. The method further comprising determining a DPD model for each subset of test cases, thereby determining the plurality of DPD models.
Claims21
A method for determining a plurality of digital predistortion (DPD) models, the method comprising:
- obtaining test data indicating a set of test cases;
- dividing the set of test cases into subsets of test cases;
- and
- determining a DPD model for each subset of test cases, thereby determining the plurality of DPD models.
A method for generating output data using a plurality of digital predistortion (DPD) models, the method comprising:
- obtaining input data;
- obtaining performance metric (PM) values wherein each PM value included in the PM values indicates performance measurement of the input data, which is obtained using one of the plurality of DPD models;
- based on the obtained PM values, selecting from the plurality of DPD models a DPD model to use for the input data;
- and
- providing the input data to the selected DPD model, thereby generating the output data.
