Systems and methods for providing signals of multiple active wireless transmitters

摘要

Systems and methods for combining signals from multiple active wireless transmitters are discussed herein. An exemplary system comprises a radio enclosure, a first transmitting RFU, a second transmitting RFU, and a combiner. The first transmitting RFU may be configured to receive a signal, upconvert the signal, compare a phase of the upconverted signal to a predetermined phase value, and adjust the phase of the signal based on the comparison to provide a first phase-adjusted upconverted signal. The second transmitting RFU may be configured to receive the signal, upconvert the signal, compare a phase of the upconverted signal to the predetermined phase value, and adjust the phase of the signal based on the comparison to provide a second phase-adjusted upconverted signal. The coupler may be configured to combine the first and second phase-adjusted upconverted signals to create an output signal and provide the output signal to an antenna for transmission.

1. A system, comprising:
a radio enclosure; a first transmitting radio frequency unit within the radio enclosure, the first transmitting radio frequency unit configured to receive a first intermediate signal based on a signal to be transmitted, upconvert the first intermediate signal to a first upconverted signal, generate a first comparison by comparing a phase of the first upconverted signal to a predetermined phase value, and adjust a phase of the first intermediate signal based on the first comparison to provide a first phase-adjusted upconverted signal; a second transmitting radio frequency unit within the radio enclosure, the second transmitting radio frequency unit configured to receive a second intermediate signal based on the signal to be transmitted, upconvert the second intermediate signal to a second upconverted signal, generate a second comparison by comparing a phase of the second upconverted signal to the predetermined phase value, and adjust a phase of the second intermediate signal based on the second comparison to provide a second phase-adjusted upconverted signal; and a coupler configured to combine the first and second phase-adjusted upconverted signals to create an output signal and provide the output signal to an antenna for transmission.
