| Abstract(in English) | The multiple-access interference (MAI) limits the transmission performance of the CDMA uplink transmission. In this paper, we propose a generalized chip-interleaved (GCI)-CDMA with 2-dimensional (2D)-OVSF spreading. Since MAI can be removed, single-user frequency-domain equalization based on the MMSE criterion can be applied for signal detection. The GCI-CDMA allows flexible multi-rate/multi-connection data transmission using either DS- or MC-CDMA. The transmission performance in a time- and frequency-selective fading multiuser environment is evaluated by computer simulation. |
