SYSTEMS AND METHODS FOR SIGNAL FREQUENCY DIVISION IN WIRELESS COMMUNICATION SYSTEMS

摘要

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.

主权项

1. A system, comprising:
an N-plexer configured to
receive from a cable a first receive signal having a first receive frequency, the first receive signal being generated from a first diversity receive signal received by at least one antenna,receive from the cable a second receive signal having a second receive frequency different than the first receive frequency, the second receive signal being generated from a second diversity receive signal received by the at least one antenna, the first diversity receive signal and the second diversity receive signal having signal diversity,provide the first receive signal to a first signal path based on the first receive frequency, andprovide the second receive signal to a second signal path based on the second receive frequency; and a modem coupled to the N-plexer and configured to
receive the first receive signal from the first signal path,receive the second receive signal from the second signal path, anddemodulate the first receive signal and the second receive signal to generate a data signal.
