ＤＳＣ機能を備えた無線通信装置及び無線通信装置のパワーセーブ方法
Document Type and Number:
Japanese Patent JP6730594
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress consumption of a battery as further as possible while driving a DSC receiver part and a voice receiver in different timing in an intermittent manner in a radio communication device comprising a DSC with the battery defined as a power source, for example.SOLUTION: A radio communication device comprises: a shared circuit 3 for applying filter processing and amplification processing to a radio wave that is received by an antenna 2; a voice signal processing circuit 4 for extracting a voice signal from a processed signal, applying predetermined processing and outputting a voice from a speaker; a DSC signal processing circuit 5 for extracting a DSC signal from the processed signal, applying predetermined digital processing, decoding and extracting the DSC signal; an intermittent drive control circuit (control circuit) 6 for driving the voice signal processing circuit 4 and the DSC signal processing circuit 5 in different patterns in an intermittent manner; and a first power source circuit 8 and a second power source circuit 9 for supplying drive power to the shared circuit 3 while any one of or both the voice signal processing circuit 4 and the DSC signal processing circuit 5 are in an active mode.SELECTED DRAWING: Figure 1
