Abstract
In an embodiment, an apparatus included in a communications system includes a transmit section including a first baseband section and a first radio frequency (RF) section, wherein the transmit section is configured to receive a calibration signal, the first RF section is configured to generate a RF calibration signal based on the calibration signal, and wherein the calibration signal comprises an orthogonal code based signal; and a receive section configured to receive the RF calibration signal over-the-air, wherein the receive section includes a second RF section and a calibration section, wherein the second RF section is configured to generate a received calibration signal based on the RF calibration signal, and wherein the calibration section is configured to determine one or more of gain, baseband delay, or RF delay compensation values, based on the inputs, to calibrate the transmit section.
