    • PROBLEM TO BE SOLVED: To reduce the power consumption by reducing a transmission output when a distance between a receiver side and a base station is short. SOLUTION: A reception level detection section 11 detects a reception level from a base station and a distance up to the base station is estimated based on the level and a gain adjustment section 12 controls a transmission amplifier 6 based on the distance estimated by the reception level detection section 11. Thus, a transmission output is varied to reduce a transmission output when a distance up to the base station is short and the power consumption is excellently reduced. A reception level rate of change detection section 13 detects a rate of change of the estimated distance by the detection section 11 and a gain adjustment inhibit section 14 inhibits transmission output variable control to make a transmission output constant when a rate of change in the estimated distance is a prescribed value or over.
    • 要解决的问题:当接收机侧和基站之间的距离短时,通过减少传输输出来降低功耗。 解决方案:接收电平检测部分11从基站检测接收电平,并且基于电平来估计直到基站的距离,并且增益调整部分12基于由接收电平估计的距离来控制发送放大器6 检测部分11.因此,当到基站的距离短并且功率消耗被显着降低时,发送输出被改变以减少传输输出。 接收电平变化率检测部13检测由检测部11进行的估计距离的变化率,增益调整禁止部14禁止发送输出变量控制,使得在估计距离的变化率 是规定值或以上。
