ABSTRACT:
A COMM system is disclosed which comprises mobile stations and a base station. The mobile station comprises; a 1st receiving and transmitting portion; a detection portion for detecting an electric power of a 1st desired wave component of the received 1st CDMA SIG; a table for storing a relation between reception power and transmission power of a 2nd CDMA SIG to be transmitted; a demodulation portion for demodulating the received 1st CDMA SIG and for detecting a CONT SIG in the desired wave; a compensation portion for compensating the relation according to the detected CONT SIG; and a transmission power CONT portion for controlling a transmission power determined according to the electric power obtained through the compensated table and the reception power. The base station comprises; a 2nd receiving and transmitting portion; an power detection portion for repeatedly detecting an electric power of a 2nd desired wave component of the received 2nd CDMA SIG; an averaging portion for averaging the repeatedly detected electric powers to obtain an average; and a CONT SIG generation portion for generating the CONT SIG according to an error between the average and a given value. The relation is corrected within a portion of range of the reception power or within a range of transmission power.
