Title:
無線装置
Document Type and Number:
Japanese Patent JP5610078
Kind Code:
B2
Abstract:
The problem is to suppress the occurrence of a communication error caused by a fluctuation in power supply voltage. A cellular phone 100 includes a wireless unit 202 that performs signal processing on a radio signal and a baseband processing unit 302 that is connected to the wireless unit 202 through a digital communication channel and transmits/receives a digital signal with the wireless unit 202 through the digital communication channel. The cellular phone 100 further includes a middleware 406 that detects whether an event causing a fluctuation in power supply voltage supplied to the wireless unit 202 or the baseband processing unit 302 is initiated. The cellular phone 100 still further includes an amplitude-level control unit 350 that increases, when the middleware 406 has detected that the event is initiated, amplitude of a digital signal transmitted/received through the digital communication channel before the event is initiated.
