Abstract:
A multi-carrier PC-CDMA system, having a plurality of mappers for mapping a plurality of data bits into PN codes corresponding to transmitting data values so as to spread the transmitting data values with predetermined PN codes and detecting PN codes from received signals to restore to original data, comprising;a transmitting part including a plurality of mixers for mixing the respective PN codes outputted from the plurality of mappers with respective frequency signals having orthogonal feature, anda receiving part including a plurality of mixers for mixing received signals with the same frequency signals mixed at the transmitting part and detecting PN codes from the signals outputted from mixers,respective mappers having different configurations from each other so as to generate an intrinsic PN code independently, regardless of PN codes outputted from the other mappers.
