<P>PROBLEM TO BE SOLVED: To obtain a spread code phase in a receiver at high speed and accurately in a spread spectrum communication system to transmit and receive a spread spectrum signal whose slot signal constituted of at least a transmission data and a pilot signal is subjected to a spread spectrum processing, and in a transmitter and the receiver constituting the system. <P>SOLUTION: The spread spectrum communication system to transmit and receive the spread spectrum signal whose slot signal constituted of at least the transmission data and the pilot signal is subjected to the spread spectrum processing increases a transmission power level to the transmitter and the receiver of a communication partner as for a signal portion to be used for obtaining the spread code phase compared with the signal portion not to be used, and the spread code phase is obtained by using the signal portion whose transmission power is increased. Phase information is obtained at high speed and accurately, therefore. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
