Method for tuning envelope tracking system and associated processing module

A method for tuning an envelope tracking (ET) system, comprising:

• determining a setting combination from a plurality of setting available to the ET system, wherein determining the setting combination from the plurality of setting available to the ET system comprises:
• determining, by a processing module, a first setting in a plurality of first settings included in the plurality of settings, and configuring the ET system by the first setting;
• and
• after the ET system is configured by the first setting, determining, by the processing module, a second setting in a plurality of second settings included in the plurality of settings, and configuring the ET system by the second setting;
• wherein the setting combination comprises the first setting and the second setting;
• and
• wherein each of the plurality of first settings is a combination of one setting selected from a plurality of first-type settings and another setting selected from a plurality of second-type settings;
• each of the first-type settings is one of an ET algorithm setting, an ET tracker setting and a power amplifier (PA) hardware setting;
• and each of the second-type settings is another of the ET algorithm setting, the ET tracker setting and the PA hardware setting.
