Abstract
In a transmitting electric power control apparatus, non-linear bias characteristic in S/N measurement is previously obtained by measurement, and a conversion table for realizing this reverse characteristic is created in an S/N measuring circuit 10, and when a measured S/N value is output from the dividing circuit 9, the table conversion circuit 1 receives this S/N value as an input and outputs a corrected S/N value from the above-described conversion table, whereby it is possible to provide the S/N
measurement with high accuracy, and this corrected and measured S/N is compared with a target S/N, and a demand for increasing and decreasing transmitting electric power is transmitted to a mobile station 53, and, in the mobile station 53, in accordance with the instruction from the base station 20, the transmitting electric power is determined and a coded information signal is transmitted.
