Abstract:
1. A system, comprising: a first transmitting radio frequency unit configured to obtain a first transmission signal based on a signal to be transmitted, adjust a first phase of the first transmission signal based on a first phase control signal to generate a phase-adjusted first transmission signal, upconvert the first transmission signal to a first upconverted signal, and generate a first comparison by comparing a phase of the first upconverted signal to a predetermined phase value to generate the first phase control signal; a second transmitting radio frequency unit configured to obtain a second transmission-signal based on the signal to be transmitted, adjust a second phase of the second transmission signal based on a second phase control signal to generate a phase-adjusted second transmission signal, upconvert the second transmission signal to a second upconverted signal, and generate a second comparison by comparing a phase of the second upconverted signal to the predetermined phase value to generate the second phase control signal; and means for combining the first upconverted signal and the second upconverted signal to create a combined signal.
