Principle of Filtering in Code-domain |

Abstract: |
Concepts of code transfer and discrete code transfer pair are proposed in this paper. Based on the linear multiuser detection in DS-CDMA systems, the authors describe the principle of filtering in code or time domain. We also point out that linear multiuser detection is a kind of filtering in code/time domain. Research on code-transfer matrix should be studied further. |
