Abstract
A signal including an RF signal and a code division multiple access signal is transmitted so that, in relation to both of the RF signal and the code division multiple access signal, a receiving end can obtain a signal having sufficiently larger power as compared with noise and with no distortion. In order to attain this object, a separation part separates the signal into the RF signal and the code division multiple access signal at a sending end. An amplification part amplifies the RF signal with an amplification factor related to its power. An amplification part amplifies the code division multiple access signal with an amplification factor related to its power. A combination part combines the amplified RF signal and the amplified code division multiple access signal with each other.
