Step S101, obtains the gain control word that the start-stop performance number of the power interval preset is corresponding.
In concrete enforcement, in advance power interval can be set according to practical situations.
In actual applications, can be scanned by the start-stop performance number of instrument to each power interval, obtain the initial power value of power interval respectively and stop gain control word corresponding to performance number.Also by testing different terminals, then can compromise, selecting a control word as initial power value respectively and stopping gain control word corresponding to performance number.The gain control word that the start-stop performance number of power interval is corresponding can also be obtained in other way, do not repeat one by one herein.
Step S102, carries out computing by the difference in described start-stop performance number and preset difference value interval, obtains the gain control word that performance number to be calibrated in described default power interval is corresponding.
In concrete enforcement, truing tool can be passed through in advance, scan the transmitting power of all gain control words.The transmitting power that transmitting power corresponding for first control word is corresponding with second control word is subtracted each other, and obtains difference, using this difference as the difference of first in difference table, corresponding with first gain control word.By that analogy, the transmitting power that transmitting power corresponding for current gain control word is corresponding with next gain control word is subtracted each other, and obtains difference, and this difference is corresponding with the mark of current gain control word, thus can obtain the difference table preset.Such as, the difference being designated K in difference table is: be designated the transmitting power that the gain control word of K is corresponding, the difference of the transmitting power corresponding with the gain control word being designated K+1.
In embodiments of the present invention, according to the start-stop performance number of the power interval preset, corresponding difference can be selected in the difference table preset interval, described start-stop performance number carried out computing with the difference in corresponding difference interval.Such as, the label of the gain control word that the initial power value of power interval preset is corresponding is X, the label stopping gain control word corresponding to performance number is Y, the label of the gain control word of the power interval namely preset all is in [X, Y] within, the difference of label in [X, Y] then can be selected in preset difference value table interval as the difference preset.
