Partial Multiuser Detection for CS-CDMA/CP over Multipath Channels and Its Comparison with DS-CDMA

Abstract

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, MUI-free transmission is guaranteed only when the data length D, channel delay L, and ZCZ length Z satisfy Z + 1 ≥ D + L, and the user population… (More)
