Abstract
The present invention provides an apparatus and method for detecting the presence of a carrier signal that is included in the reverse signals of a communications system. The present invention uses an improved apparatus that determines the average power of the reverse signals during a predetermined counting cycle. The average power is then compared to a threshold power value. If the average power exceeds the threshold power value, an enable signal is provided to allow further transmission of the reverse signals.
