<P>PROBLEM TO BE SOLVED: To suppress deterioration in reception quality by performing communication at a high SINR while suppressing increase in power consumption, even in a state that a disturbing wave from a transmission circuit in a radio communication device is input to a reception circuit in the same casing. <P>SOLUTION: A gain adjustment part 320 adjusts gain of an LNA 230 based on correspondence between the gain of the LNA 230 and an SINR which are mapped to transmission power of a cellular signal and reception power of a radio LAN signal. An SINR calculation part 321 calculates the correspondence between the LNA gain and the SINR by using cellular transmission power information and information on the reception power of the radio LAN signal. A gain setting part 322 adjusts the gain of the LNA 230 based on the correspondence. <P>COPYRIGHT: (C)2013,JPO&INPIT |
