摘要：
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.
