<P>PROBLEM TO BE SOLVED: To obtain a radio communication apparatus capable of exhibiting an adjacent channel leakage power detection function without increasing the number of circuits. <P>SOLUTION: A switch 11 selects a feedback signal FB of a transmission signal TX as a selection signal S11 in a transmission period. An FFT section 16A in a receiving processing unit 15 performs FFT processing for a twice oversampling signal SD2 (based on the feedback signal FB of the transmission signal TX) in the transmission period to obtain a transmission spectrum TS1. An ACP detector 12 detects the existence/absence of an ACP based on the transmission spectrum TS1 in the transmission period and outputs a level control signal LC12 for indicating an output level of a transmission processing part 2 and an ON/OFF control signal NF12 for instructing ON/OFF of a radio unit 6 and a high power amplifier 7. <P>COPYRIGHT: (C)2009,JPO&INPIT |
