Array antenna adaptive digital pre-distortion with bayesian observation analysis

An apparatus, comprising:

• at least one processor;
• and
• at least one memory comprising computer program code,
• the at least one memory and computer program code being configured, with the at least one processor, to cause the apparatus at least to
• select a plurality of patch elements from an array antenna of a network element;
• determine an accuracy confidence value for each patch element;
• generate a set of coefficients of the array antenna;
• generate an ensemble of non-linear forward models using the accuracy confidence value and the set of coefficients;
• generate an array of pre-distortion signals using the ensemble of non-linear forward models;
• and
• configure each antenna of the array antenna with a corresponding pre-distortion signal from the array of pre-distortion signals.
