Abstract:
A communication apparatus comprising:receiving and transmitting means having an antenna for receiving a first CDMA radio wave signal, detecting a desired wave component including a control signal from said first CDMA radio wave signal, and transmitting a second CDMA radio wave signal;detection means for detecting an electric power of the detected desired wave component;table means for storing a relation between said detected electric power and an electric power of said second CDMA radio wave signal to be transmitted, said control signal indicating compensation of said relation;demodulating and detection means for demodulating the detected desired wave component and outputting demodulation data and for detecting said control signal from the detected desired wave component;compensation means for compensating said relation in accordance with said detected control signal;determining means for determined an actual electric power of said second CDMA radio wave signal to be transmitted in accordance with the compensated said relation; andtransmission power control means for controlling a transmission power of said second CDMA radio wave signal in accordance with said actual electric power.
