Techniques for multi-head adaptive controller with shared parameters

An apparatus comprising:

• processor circuitry configured to:
• receive by at least one processor running a digital predistortion (DPD) model of a transceiver, a DPD input, the transceiver including a power amplifier (PA);
• output, from the at least one processor and in response to the DPD input, a first DPD output of the DPD model;
• cause the PA to generate a PA output based on the first DPD output;
• update the DPD model based on the DPD input, the DPD output and the PA output;
• receive, after the DPD model is updated, the DPD input by the at least one processor;
• output, by the at least one processor, a second DPD output based on the DPD input;
• and
• cause wireless communication by the transceiver to a network device based on the second DPD output.

One or more non-transitory, computer-readable media comprising a sequence of instructions that, when executed, cause processor circuitry to:

• receive by at least one processor running a digital predistortion (DPD) model of a transceiver, a DPD input, the transceiver including a power amplifier (PA);
• output, from the at least one processor and in response to the DPD input, a first DPD output of the DPD model;
• cause the PA to generate a PA output based on the first DPD output;
• update the DPD model based on the DPD input, the DPD output and the PA output;
• receive, after the DPD model is updated, the DPD input by the at least one processor;
• output, by the at least one processor, a second DPD output based on the DPD input;
• and
• cause wireless communication by the transceiver to a network device based on the second DPD output.
