Abstract:
A transmission electric power control device comprising:coupling means which extracts a part of a transmitting signal; detection means which detects a signal extracted by said coupling means; error detecting means which compares the detection signal with a reference value and outputs an error signal; transmission electric power designation means which outputs transmission electric power designation information; control calculation parameter generating means which generates a control calculation parameter corresponding to said transmission electric power designation information; control calculation means which modifies said error signal according to said control calculation parameter and outputs a control variable; a transmission electric power control means for generating a transmission electric power control signal according to the transmission electric power designation information output from said transmission electric power designation means; control variable addition means which adds said control variable with said transmission electric power control signal; and gain variable means which controls a gain according to the output of said control variable addition means; wherein said coupling means, detection means, error detecting means, transmission electric power designation means, control calculation parameter generating means, control calculation means, control variable addition means, transmission electric power control means, and gain variable means constitute a feedback loop so as to perform automatic transmission electric power control.
