Abstract(in English) | Multiuser interference (MUI) limits the transmission performance of the DS-CDMA uplink. In this paper, we propose a 2-dimensional (2-D) OVSF spreading and chip-interleaving to transform the multi-user channel into orthogonal single-user channels. Due to MUI cancellation, the chip-interleaved DS-CDMA with 2-D OVSF spreading has ability to increase the link capacity as well as to provide multi-rate services. Single-user frequency-domain equalization based on the minimum mean square error (MMSE) criterion is applied for signal detection. The transmission performance in a multiuser and frequency-selective fading environment is evaluated by computer simulation. |
