    摘要： 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.

    摘要： In accordance with the present disclosure, disadvantages and problems associated with controlling signal transmission of a wireless communication device may be reduced. In accordance with an example embodiment of the present disclosure a method for controlling transmission of a wireless communication signal comprises sensing one or more signals indicative of a power level of a wireless communication signal. The power level of the wireless communication signal is amplified by a power amplifier according to an amplifier control signal. The method further comprises determining a change in the power level based on the one or more signals indicative of the power level. The change is associated with one or more perturbations of the amplifier control signal. The method also comprises adjusting transmission of the wireless communication signal according to the change in the power level.
