摘要： A propagation loss measuring section 207 appropriately changes a measuring method according to the reception type of system informed from a base station so as to measure propagation losses. A propagation loss comparator 209 compares the propagation loss between the respective cells. A transmission slot controller 210 controls a data assembling section 211 and spreader 213 in such a way to transmit a signal to a base station existing in a cell with a smaller propagation loss. A transmission power controller 208 controls a RF section 202 in such a way to transmit a signal with a transmission power value obtained by adding the propagation loss value at each cell to a target reception power value at each base station.

摘要： A search unit of a receiver synchronizer includes a search PN signal generator for generating PN signals for all PN phases in order to search the maximum power path; a search correlation unit which outputs a correlation value from sampling data and the PN signal; a data buffer for storing the correlation value; a path search unit for controlling a search the path using the correlation value received from the data buffer; a PN signal generator for outputting a PN signal to a DLL and a data demodulation correlation device; and a DLL switch for switching the PN phase to the phase of the maximum power path by controlling the PN signal generator as a result of the search for the path. The PN phase of the PN signal output to the DLL is constantly maintained in synchronization with the phase of the maximum power path.
