    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.

    Abstract: Systems and methods for transceiver communication are discussed herein. A filter module may be configured to filter each carrier signal of a multicarrier transmit signal with a different bandpass filter, each bandpass filter configured to filter a different frequency band. A carrier control module may be configured to control the plurality of bandpass filters of the filter module using a carrier selection signal to enable or disable each bandpass filter, thereby coupling carrier signals of the multicarrier transmit signal to a first set of bandpass filters and decoupling a second set of bandpass filters. Filtering the carrier signals of the multicarrier transmit signal is performed by the first set of bandpass filters while the decoupling of the second set of bandpass filters limits energy in the respective frequency band. An antenna may be configured to transmit the filtered multicarrier transmit signal.

    Abstract: An interference detection system comprises memory storing computer instructions to cause a processor to perform gathering a temporal snapshot of radio parameter values associated with a first site of a point-to-point radio system, the radio parameter values including at least a receive signal level (RSL) value and at least one other radio parameter value correlated with signal degradation; determining whether the RSL value is greater than an RSL threshold; determining whether the other radio parameter value indicates a threshold level of signal degradation; when the RSL is greater than the RSL threshold and the other parameter indicates a threshold level of signal degradation during the temporal snapshot, determining that external interference is present during the temporal snapshot; when the RSL is not greater than the RSL threshold, determining that the external interference is not present; and performing a responsive action to a determination of the external interference being likely present.
