Abstract
Variable gain circuits 16A and 16B are provided, respectively, on an output side of spreading circuits 15A and 15B disposed for each code channel, and after the outputs from the variable gain circuits 16A and 16B are added by adders 17 and 18, orthogonal modulation is applied to the outputs by a modulator 20, and a transmission signal is obtained. Furthermore, a variable gain circuit 22 for adjusting a level of the transmission signal is provided. An adjustment of average transmission power of the code channels is conducted by the variable again circuit 22, and an individual adjustment is conducted by the variable gain circuits 16A and 16B.
