INTER-ANTENNA INTERMODULATION NOISE SIGNAL REDUCTION METHOD AND COMMUNICATION TERMINAL DEVICE USING THE METHOD CAPABLE OF OPTIMIZING A DATA TRANSMISSION RATE WHILE PREVENTING QUALITY REDUCTION OF VOICE COMMUNICATION AND VOICE CALL DISCONNECTION

摘要

PURPOSE: Inter-antenna intermodulation noise signal reduction method and communication terminal device using the method are provided to confirm a signal to noise ratio (SNR) in real time and to control intensity of long term evolution (LTE) transmission power according to the confirmed SNR.;CONSTITUTION: A detection unit (120) measures an SNR of communication related to a second channel. A judgment unit (130) judges whether the SNR is less than a first threshold value or not. When the SNR is less than the first threshold value, an output control unit (140) decreases output signal intensity of a first channel. When the judgment unit judges that the SNR exceeds the first threshold value, the output control unit increases the output power intensity of the first channel to be the same as the first threshold value.;COPYRIGHT KIPO 2013;[Reference numerals] (110) Communication signal processing unit; (111) First transceiver unit; (112) Second transceiver unit; (120) Detection unit; (130) Judgment unit; (140) Output control unit
