摘要：
An automatic gain control device includes an amplifier for a reception signal, a signal processing unit, a memory, and a control unit. The amplifier can set a gain. The signal processing unit extracts control data from an output from the amplifier and performs information processing for the data. The memory stores the gain setting value of the amplifier. The control unit controls the gain of the amplifier in accordance with a preset control algorithm. On the basis of the result obtained when the control unit computes a gain setting value stored in the memory in accordance with a preset algorithm, the control unit controls the gain of the amplifier in correspondence with operation of switching the frequency of a reception signal, which is accompanied by different frequency monitoring in the compressed mode by the signal processing unit. A radio communication terminal, a control method for an automatic gain control device, a control program for an automatic gain control device, an automatic gain control method, a radio communication system, and a radio communication method are also disclosed.
摘要（中）：

自动增益控制装置包括用于接收信号的放大器，信号处理单元，存储器和控制单元。 放大器可以设置增益。 信号处理单元从放大器的输出中提取控制数据，并执行数据的信息处理。 存储器存储放大器的增益设置值。 控制单元根据预设的控制算法来控制放大器的增益。 基于当控制单元根据预设算法计算存储在存储器中的增益设定值时获得的结果，控制单元根据接收信号频率的切换操作来控制放大器的增益，其中 伴随着信号处理单元在压缩模式下的不同频率监视。 还公开了无线电通信终端，自动增益控制装置的控制方法，自动增益控制装置的控制程序，自动增益控制方法，无线电通信系统和无线电通信方法。
