<p>The present invention relates to a CDMA wireless base station apparatus. An object of the present invention is to provide a CDMA wireless base station apparatus which is able to shorten the period from a fault to recovery. Each of a 0-system spread processing section 3a and a 1-system spread processing section 3b which constitute a duplex configuration generates a perch channel signal, an active synthesized spread signal and a standby synthesized spread signal. In normal operation, the perch channel signal and the active synthesized spread signal from the 0-system spread processing section 3a and the standby spread signal from the 1-system spread processing section 3b are synthesized in a radio transmission processing circuit 4 and radiated from an antenna 5. When a fault occurs in the 0-th spread processing portion 3a, a switching control is performed so that the perch channel signal, the standby synthesized spread signal and the active synthesized spread signal from the 1-system spread processing section 3b are transmitted from the radio transmission processing circuit 4. The radio transmission processing circuit 4 radiates the perch channel signal, the standby synthesized spread signal and the active synthesized spread signal from the antenna 5. According to the present invention, the period need for recovery is shortened. <IMAGE></p> |
