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 $Z+1 \ge D+L$.
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. |
