Calibrating transmit error vector magnitude using over-the-air loopback

A method for wireless communications, comprising:

• providing first intermediate frequency (IF) signals to a radio frequency (RF) module for use in generating first RF signals for transmission via an antenna element;
• obtaining second IF signals generated based on the first RF signals;
• determining a transmit performance metric for the RF module based on the first IF signals and the second IF signals;
• determining a first transmit power level based on the determined transmit performance metric;
• and
• causing the RF module to generate second RF signals at the first transmit power level for transmission via the antenna element.

An wireless station, comprising:

• first and second antenna elements;
• a first radio frequency (RF) module configured to:
• generate first RF signals based on first intermediate frequency (IF) signals, and
• transmit the first RF signals via the first antenna element;
• a second RF module configured to:
• receive the first RF signals via the second antenna element, and
• generate second IF signals based on the first RF signals as received via the second antenna element;
• and
• a baseband module configured to:
• determine a transmit performance metric for the first RF module based on the first IF signals and the second IF signals,
• determine a first transmit power level based on the determined transmit performance metric, and
• cause the first RF module to generate second RF signals for transmission via the first antenna element at the first transmit power level.
