    • A received power calculating section and a sending power calculating section calculate a received power value Rcv_Power(t) and a sending power value Snd_Power(t) by respectively adding predetermined gain values when the received power calculating section and the sending power calculating section calculate the received power value Rcv_power(t) and the sending power value Snd_Power(t). A received detection value control section and a sending detection value control section control the calculated receiving detection value and the sending detection value and set the received detection value and the sending detection value so as not to become less than a predetermined lower limit value, respectively.
    • 接收功率计算部分和发送功率计算部分在接收功率计算部分和发送功率计算部分计算接收到的功率计算部分和发送功率计算部分时分别计算接收功率值Rcv_Power(t)和发送功率值Snd_Power(t) 功率值Rcv_power(t)和发送功率值Snd_Power(t)。 接收检测值控制部分和发送检测值控制部分控制所计算的接收检测值和发送检测值,并将接收到的检测值和发送检测值分别设定为不小于预定的下限值。
