Abstract
Techniques for calibrating in-band and out-of-band receivers using complex signals. The techniques include receiving a signal from a wireless radio antenna at a first receiver and a second receiver in a wireless communication system. The first receiver is configured to receive in-band transmission during operation of the wireless communication system and the second receiver is configured to receive out-of-band transmission during operation of the wireless communication system, and the signal is transmitted at least partially simultaneously from the wireless radio antenna to the first receiver and the second receiver. The techniques further include determining a difference of complex signals for the first receiver and the second receiver based on measuring the signals received from the wireless radio antenna at the first receiver and the second receiver, and calibrating the second receiver with the first receiver based the difference of complex signals.
