Abstract:
A mobile communication system comprising:a base station; anda plurality of mobile devices;wherein said base station comprises:means for detecting a carrier signal point represented by an in-phase component and a quadrature component at regular intervals;means for correcting an amplitude of said carrier signal point detected by said detecting means according to previous transmission power control values;means for predicting a carrier signal point at a time point when next control for transmission power is executed by using said carrier signal point whose amplitude is corrected by said correcting means;means for comparing an electric power of said carrier signal point predicted by said predicting means with a predecided reference value;means for generating a control value for said transmission power at said time point when said next control for transmission power is executed, based on said compared result given by said comparing means;a memory for storing said control value for transmission power generated by said generating means and supplying said previous control values for transmission power to said correcting means;means for transmitted said control value for transmission power; andwherein said plurality of mobile devices are connected to said base station through a radio wave of one frequency so that said mobile devices are controlled to keep signal electric powers received by said base station identical with each other according to said control value for transmission power transmitted from said base station.
