摘要： A base station of a CDMA communication system includes a transmission de-correlator for eliminating interferences between communication channels of a downlink. The transmission de-correlator has a memory storing a set of data representative of the products of transmission information bits for the respective channels, and the sums of the products of the spread code data sequences for the respective channels, and the elements of an inverse matrix with respect to a predetermined matrix of a cross-correlation between the spread code data sequences for the respective channels. The sums correspond to additions of the products along a direction of columns or to additions of the products along a direction of rows of the inverse matrix. A counting device is operative for causing the memory to sequentially output the data therefrom. An adder serves to calculate a sum of the data outputted from the memory.

摘要： When a power supply of a mobile radio apparatus is turned on, a power supply change-over switch of a power supply control unit is changed over to the side of a pager unit to turn on only a power supply of the pager unit, so that a pager network which does not require position registration is utilized to perform intermittent receiving operation with low power consumption. When there is an incoming call to the pager unit, a CPU of the power supply control unit receives an incoming control signal from a pager decoding circuit and changes over the power supply change-over switch to the side of a radio-telephone line terminal unit to turn on the radio telephone line terminal unit and turn off the pager unit. The CPU sends a control signal to a timing control circuit of the radio-telephone line terminal unit so that the position registration is performed by utilizing a mobile radio network and an operation mode of the mobile radio apparatus proceeds to a usual talking mode. After a pager calling has been performed in a calling side, the mobile radio apparatus is called by the portable telephone number and talking is then is made. When the talking has been finished, the CPU receives a control signal from the timing control circuit and changes over the power supply change-over switch to the side of the pager unit again to turn on the pager unit to enter a waiting state for reception.

摘要： Disclosed is a method and an apparatus for controlling transmission electric power capable of minimizing a decrease in the amount of maximum transmission electric power without degrading an adjacent channel leakage power ratio when code-multiplexing additional control information with data and main control information. A mobile device checks values of gain factors βd and βc when performing code multiplexing to transmit signals from channels DPDCH to transmit data, DPCCH to transmit main control information, and HS-DPCCH to transmit additional control information. A maximum transmission electric power is decreased at a plurality of levels based on the check result and a ratio (Δhs) between the gain factors βc and βhs. It may be preferable to check the presence or absence of transmission data instead of the gain factor βd. In this case, when no transmission data is available, the maximum transmission electric power is decreased at a plurality of levels based on Δhs. When transmission data is available, the maximum transmission electric power is decreased at a plurality of levels based on the gain factor βc and Δhs.

摘要： Removing adverse effects in case error detection using error detection codes cannot be performed correctly, and improving the data transmission efficiency. The turbo decoder 6 compares data which is decoded this time with data which is decoded previous time, both of which are decoded in repetitive decoding processing, to obtain discord number information indicative of the number of discordant sign bits, and sends the information to a terminal I/F unit 7 and a packet flow retransmission controlling unit 10. Even though it is determined that error detection result from a CRC recalculating unit 9 shows that there exists no bit error, in case the number of discordant sign bits is larger than a predetermined threshold value, it is determined that there is generated error. And, a packet flow retransmission controlling unit 10 sends a signal requesting retransmission of data. Furthermore, data amount to be retransmitted is varied in accordance with the number of discordant sign bits to improve the data transmission efficiency.
