Abstract(in Japanese) (See Japanese page)
Abstract(in English) Result of numerical simulation for CDMA carrier signal separation using ICA (independent component analysis) is reported. In separation of conventional CDMA carrier signals generated by LFSRs (linear feedback shift registers), separation performance become seriously worse when the phase difference is close to a multiple of 90°. On the other hand, in separation of chaos CDMA carrier signals based on non-binary spreading sequences generated by chaotic dynamical systems, separation performance is satisfactory regardless of phase difference.
