SYSTEMS AND METHODS FOR EMULATING UPLINK DIVERSITY SIGNALS

摘要

A signal interface unit for interfacing uplink downstream signals from a downstream device with an upstream device includes at least one upstream interface configured to communicate a primary uplink upstream signal and at least one emulated-diversity uplink upstream signal to an upstream device; a downstream interface configured to receive an uplink downstream signal from a downstream device; wherein the signal interface unit is configured to convert the uplink downstream signal into the primary uplink upstream signal; wherein the signal interface unit is further configured to generate the at least one emulated-diversity uplink upstream signal from at least one of the primary uplink upstream signal and the uplink downstream signal.
