In this paper, convolutional spreading CDMA with cyclic prefix (CS-CDMA/CP)\r\nemploying the zero-correlation-zone (ZCZ) code generated from the Chu sequence\r\nis proposed as a novel multi-access scheme for fast fading multipath channels. \r\nAnalysis results demonstrate that the system remains approximately multiuser interference (MUI)-free \r\neven when the system is heavily loaded and \r\nsubject to severe Doppler spreads.\r\nAn effective channel estimation method based on B-spline approximation is also proposed.\r\nSimulation results show, in combination with the Probabilistic Data Association (PDA) equalization,\r\nthe system significantly outperforms the DS-CDMA system \r\nemploying Linear Minimum Mean Squared Error (LMMSE) chip-wise equalization and polynomial interpolation-based\r\nchannel estimation from medium to high user population. |
