Embodiment Construction

[0037]The first figure is a mobile communication device 1 for automatically calibrating output power of the present invention, which includes a receiver 12 , a computing unit 14 , a memory 16 , and a converter 18 . The receiver 12 uses the antenna to receive the signal, and outputs the transmission channel 102 and the transmission power level 103 assigned by the base station to the calculation unit 14 . The memory 16 stores two comparison tables 161 and 162. The comparison table 161 stores the scaling factor corresponding to each power level when a reference channel transmits data, and the comparison table 162 stores a reference The delta scaling factor between the reference channel and other channels at the reference power level. The reference channel referred to here is usually the middle channel among all available transmission channels, and the scale factor is a digital calculation unit. After receiving the transmission channel 102 and the transmission power level 103 , t...

Abstract

The apparatus thereof comprises: a receiver, a memory, a calculation unit and a converter; wherein, the receiver is used for receiving a power level of transmission channel and transmission power sent from base station; the memory is used for saving a proportion factor corresponding to the reference channel and a differential value between said proportion factor and its corresponding reference power level; the calculation unit is used for searching a relevant proportion factor and a differential value of proportion factor from the memory in term of the power level of transmission channel and transmission power sent from the receiver, and figured out a digital control value that is outputted to the converter; the converter is used to convert the digital control value to a voltage value used to control the emitting power size of mobile communication equipment.

Description

technical field [0001] The present invention relates to a method and device for automatically calibrating the output power of a mobile communication device. The present invention is particularly concerned with using interpolation to quickly and accurately estimate the output power required by a mobile communication device to transmit a signal, so that the mobile communication device can adjust to the appropriate power to transmit the signal. Background technique [0002] The specifications set by the European Telecommunication Standard Institution (ETSI) standardize the absolute power of the fourth-class mobile communication equipment (class 4mobile) of the Global System for Mobile Communication (GSM) at various power control levels. Output Power. The GSM system utilizes dynamic power control to ensure that each connection can maintain a minimum but sufficient power not to affect the received power. Adjusting and maintaining the power of the mobile communication device to ...
