ABSTRACT:
The radio base station apparatus includes a first despreading processing circuit for despreading a first control channel (DPCCH) signal; a second despreading processing circuit for despreading either a second control channel (HS-DPCCH) signal or a third control channel (E-DPCCH) signal; a third despreading processing circuit capable of despreading the first control channel signal, the second control channel signal and the third control channel signal; a first scrambling code generation circuit for supplying a common scrambling code to both the first despreading processing circuit and the second despreading processing circuit; and a second scrambling code generation circuit for supplying to the third despreading processing circuit a scrambling code which is different from the scrambling code generated in the first scrambling code generation circuit.
