| Abstract(in English) | This paper investigates the single-user receiver with co-channel interference (CCI) canceller based on the orthogonalizing matched filter (OMF)using the multi-dimensional lattice filters for DS/CDMA in a multipath environment. The OMF can output multiusers' interfering signals not containing the desired user's one in an AWGN channel, using knowledge of only the desired user's spreading codes. However, the OMF cannot always eliminate the desired user's signal in a multipath channel. In this paper, we analyze the property of the OMF and derive a condition on parameters for extension to the proposed receiver in a multipath channel. The proposed receiver can apply orthogonality property of the OMF to not only a direct wave but also delayed waves. Computer simulations show the proposed receiver have capability to cancel the CCI and convergent fast in a multipath channel. |
