Systems and methods for combining signals from multiple active wireless receivers
First Claim
1. A system comprising:
- a first receiving radio frequency unit configured to;
receive, via a first antenna, a signal from a wireless communication source, the signal from the wireless communication source being received by the first antenna at a first phase,compare the first phase of the signal as received by the first antenna to a predetermined phase value, andadjust the first phase of the signal as received by the first antenna to generate a first phase-adjusted signal;
a second receiving radio frequency unit configured to;
receive, via a second antenna, the signal from the wireless communication source, the signal from the wireless communication source being received by the second antenna at a second phase, the first phase and the second phase being different,compare the second phase of the signal as received by the second antenna to the predetermined phase value, andadjust the second phase of the signal as received by the second antenna to generate a second phase-adjusted signal, the second phase-adjusted signal and the first phase-adjusted signal having substantially similar phase; and
a signal combiner configured to combine the first phase-adjusted signal and the second phase-adjusted signal to generate a combined signal.

Abstract
Systems and methods for combining signals from multiple active wireless receivers are discussed herein. An exemplary system comprises a first downconverter, a phase comparator, a phase adjuster, and a second downconverter. The first downconverter may be configured to downconvert a received signal from a first antenna to an intermediate frequency to create an intermediate frequency signal. The phase comparator may be configured to mix the received signal and a downconverted signal to create a mixed signal, compare a phase of the mixed signal to a predetermined phase, and generate a phase control signal based on the comparison, the downconverted signal being associated with the received signal from the first antenna. The phase adjuster may be configured to alter the phase of the intermediate frequency signal based on the phase control signal. The second downconverter may be configured to downconvert the phase-shifted intermediate frequency signal to create an output signal.
