Abstract(in English) | Convolutional spreading CDMA with cyclic prefix (CS-CDMA/CP) enables multiuser interference-free (MUI-free) transmission over multipath downlink channels with the use of zero correlation zone (ZCZ) codes. However, CS-CDMA/CP guarantees MUI-free transmission only when the data length D, channel delay L, and ZCZ length Z satisfy Z+1≧D+L. In this paper, we investigate the MUI characteristics of CS-CDMA/CP employing M-ZCZ codes and propose an iterative partial multiuser detection for it. Comparison with the DS-CDMA shows that the CS-CDMA/CP offers a better tradeoff between the performance and receiver complexity, which indicates its potential application in future wireless communications. |
