<P>PROBLEM TO BE SOLVED: To obtain a receiver receiving a spread signal by CDMA system in which correlation between the data of a received spread signal and the data of a specified spread code is operated effectively. <P>SOLUTION: In the circuit of a despread unit of the receiver, number of bits switching correlation operating means 1-14 operate correlation between the data of a received spread signal and the data of a specified spread code while switching the number of bits of the data of a received spread signal becoming the object for operating correlation with the data of a specified spread code depending on the number of users, the number of paths or the spreading factor, for example. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
