    Abstract: In a wireless communication apparatus in a time division duplex system, a transmission signal generation unit generates a transmission signal. A power amplifying device amplifies the generated transmission signal. A control signal generation device generates a drain voltage control signal for control of the drain voltage of the power amplifying device, and a gate voltage control signal for control of the gate voltage of the power amplifying device. The switch unit switches off the drain power supply of the power amplifying device during reception in the time division duplex system according to the drain voltage control signal. In addition, the power amplifying device sets a higher gate voltage during reception in the time division duplex system higher than during transmission according to the gate voltage control signal.

  • Publication number: 20100325733
    Abstract: Hindrance of normal execution of a process caused by unexpected processing of a signal handler can be prevented. When an instruction 1121 arranged in a function 1125 which might allow unexpected processing of a signal handler to prevent normal execution of a process is executed, a signal handler table of the process is changed to make a signal handler executed during the processing of the function 1125 be a signal handler hook function. When a signal is generated to execute the signal handler hook function, unexpected processing of the signal handler is prevented by executing an original signal handler after changing a security level of the process to a security level not allowed to execute unexpected processing. For ending the function 1125, a second specific instruction 1122 is executed to return the signal handler table to a former state.
