摘要： There are provided a channel estimation unit for achieving highly accurate channel estimation, a CDMA receiver and a CDMA transceiver with the channel estimation unit. Channel estimates of data symbols are obtained from pilot symbols in a combined symbol sequence which has a plurality of slots and includes the data symbols and the pilot symbols. First, the pilot symbols in the combined symbol sequence are located. Second, pilot blocks are generated by extracting the pilot symbols from two or more slots in the combined symbol sequence. Third, channel estimates of the data symbols are obtained by calculating a weighted sum of averages of the pilot symbols in the individual pilot blocks. The weighted sum is carried out using appropriate weighting factors for individual data symbols in each slot. This enables highly accurate channel estimation.

摘要： When packet sending and receiving apparatus 21 sets a connection, timing control apparatus 22 generates a timing information Tf as the packet is dispersed equivalently. Timing control apparatus 22 notices the timing information Tf to packet sending and receiving apparatus 21 and base station 3. Packet sending and receiving apparatus 21 carries out a packet generating processing in accordance with a frame offset value which is indicated by the timing information Tf. Therefore, the packets in which a packet transmission timing is averaged in a packet transmission period arrives to packet multiplex apparatus 23. Consequently, it is possible to decrease a waiting time of the packet multiplex transmission. Therefore, it is possible to use efficiency a transmission link L1, while being satisfied the required service quality.

摘要： Received baseband signals from a plurality of antennas 11 1 to 11 Q are linearly combined through multiplication by weighting coefficients, then a decision signal is delayed for one symbol duration, and the delayed signal is multiplied by a feedback filter coefficient w b * to generate intersymbol interference, which is subtracted from the linearly combined output y(i). The subtracted output is subjected to a signal decision to obtain a decision signal, then the difference between the input into a decision unit 17 and the decision signal is obtained as an error signal e(i), and weighting coefficients w 1 * to w Q * and the feedback filter coefficient w b * are estimated in a parameter estimation part 71 so that the square of the error signal e(i) is minimized. At the transmitting side a transmitted signal is delayed for 1T and is then multiplied by the feedback filter coefficient w b *, then intersymbol interference is subtracted from the transmitted signal to distort it, and the distorted signal is multiplied by the weighting coefficients w 1 * to w Q *, respectively, thereby creating transmitted baseband signals for application to the antennas 11 1 to 11 Q .

摘要： To register current codec types of a mobile station with a network side, the mobile station 11 notifies, when it conducts the location registration or a mobile user replaces his or her old mobile station, a visitor location switching system 5, which is associated with the current location of the mobile station, of the codec types supported by the mobile station 11 using a mobile communication control signal between the mobile station and the mobile network. Receiving the notification, the visitor location switching system 5 enters the update of the codec types into a location register 41 in a memory home station that controls the mobile network 2. The codec types can be thus registered into the mobile network 2 using the mobile communication control signal. Since the mobile network 2 can always acquire the latest codec types for the mobile station, the discrepancy is canceled between the codecs the mobile station supports and the codecs the network registers.

摘要： A branch candidate selecting method by a mobile station and a diversity handover control method on a network side in DHO performance are provided which consider a maximum cable branch number and a maximum radio branch number of the mobile station, when the mobile station detects a plurality of addition branch candidates and deletion branch candidates. The mobile station inserts a plurality of addition branch candidates and deletion branch candidates, that is, all the DHO candidates into one handover trigger signal, and notifies the network. The addition branch candidates are put into addition information parameters in the handover trigger signal, and the deletion branch candidates are put into deletion information parameters. To simplify processing on the network side, the network side separates the addition branch candidates from the deletion branch candidates, and carries out sequential processing of them independently.
