<P>PROBLEM TO BE SOLVED: To provide a CDMA communication system which does not require preparation of a complicate Rake receiving circuit in a mobile station, in a communication system conducting a Pre-Rake processing on the side of a base station. <P>SOLUTION: The CDMA communication system is composed of the base station 100 and a mobile station 200, and the side of the base station 100 is premised on a system having a Pre-Rake section 104 conducting the Pre-Rake processing. A processing in a frequency region is conducted by an FFT 203, an FDE 204 and an IFFT 205 on the side of the mobile station 200 for avoiding a complicate Rake receiving processing on the side of the mobile station 200. Consequently, the system fits a CP inserting 103 adding a cycle prefix to a symbol diffused by a diffuser 102 on the side of the base station 100, and a CP remover 202 removing the cycle prefix on the side of the mobile station 200. <P>COPYRIGHT: (C)2007,JPO&INPIT |
