Abstract: A hardware is used to perform an SSDT processing, thereby avoiding performance degradation than otherwise would occur due to load increase caused by a software processing, and thereby realizing a base station that can instantaneously perform a transmission control and provide a high speed site selection. In order to perform a site selection diversity power control (SSDT) for the purpose of reducing the amount of interference that would be caused by transmitting the same data to a plurality of cells or antennas during soft-handover, an encode processing part (1) is used to add a transmission control bit to the transmitted data. In response to this transmission control bit, a transmission control signal selecting circuit (206) selects a transmission control signal of destination.

Abstract: A programmable device connected to a storage unit which stores logic circuit configuration information to form a logic circuit and control circuit configuration information to form a control circuit includes a first programmable logic device and a second programmable logic device, and a configuration unit which forms the control circuit in the first programmable logic device, by providing the control circuit configuration information in the storage unit to the first programmable logic device. The control circuit formed in the first programmable logic device forms the logic circuit in the second programmable logic device, by providing the logic circuit configuration information in the storage unit to the second programmable logic device.

Abstract: A communication control apparatus of a CDMA base station system, include a control section and a transmission signal processing section. The control section generates a first transmission start signal to instruct start of software hand-over for a mobile station which is communicating. The transmission signal processing section determines a current time period from at least one previous time period in response to the first transmission start signal, and generates a second transmission start signal after the determined current time period from reception of the first transmission start signal. The previous time period is measured in the transmission signal processing section. A transmission signal is transmitted from the communication control apparatus to the communicating mobile station in response to the second transmission start signal.

Abstract: 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.
