APPARATUS FOR CONTROLLING DUMMY FREQUENCY POWER IN CDMA COMMUNICATION SYSTEM AND HARD HANDOFF METHOD

摘要

PURPOSE: A dummy frequency power controlling apparatus is provided to adjust an appropriate coverage of a dummy frequency by adjusting an output level of the dummy frequency considering a traffic of a using frequency. CONSTITUTION: A dummy frequency power controlling apparatus is described in which an automatic gain controller(100) receives a radio frequency signal of a using frequency to control a level of the received radio frequency signal at a predetermined power level. The first frequency converting part(200) converts the radio frequency signal from the controller(100) into a signal of an intermediate frequency band. An automatic power level controller(300) amplifies the intermediate frequency signal according to a control signal from a microprocessor(500) considering a service coverage of a service frequency signal. The second frequency converting part(400) converts the intermediate frequency signal from the controller(300) into a dummy frequency signal having a radio frequency level.
