Abstract
An uplink signal processing system and method of operating the same includes a primary signal processing circuit generating a primary output signal and a secondary signal processing circuit generating a secondary output signal. The uplink signal processing system includes a switch communicating with the primary signal processing circuit and the secondary signal processing circuit. A monitoring and control system monitors the primary signal processing circuit and the secondary signal processing circuit and generates a monitoring signal and controlling the switch to switch from the primary signal processing circuit to the secondary signal processing circuit in response to the monitoring signal. The switch forms an output signal in response to switching.
