摘要
The radio reception apparatus of the present invention obtains a despread signal of the reception signal with a high spreading factor by carrying out a correlation calculation using codes with a relatively low spreading factor and then carrying out multiplications/additions, thereby eliminating the need for a large-scale correlation circuit (processing circuit) even when using a relatively high spreading factor in a DS-CDMA (Direct Sequence CDMA) system, which uses layered (code treed) orthogonal spreading codes.
