Abstract: A system may include at least one antenna for receiving a first receive signal having a first signal diversity property and a second receive signal having a second signal diversity property. A first signal path may include a first frequency converter for downconverting the first receive signal to a first intermediate frequency signal having a first intermediate frequency. A second signal path may include a second frequency converter for downconverting the second receive signal to a second intermediate frequency signal having a second intermediate frequency. A transducer module may route the first receive signal to the first signal path, and route the second receive signal to the second signal path. A first N-plexer may select the first intermediate frequency signal or the second intermediate frequency signal for transmission to a cable, and to provide a data signal based on a selected intermediate frequency signal to the cable.

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.
