A Multicarrier DS-CDMA System Using Both Time-Domain and Frequency-Domain Spreading

Yang, L-L., Hua, W. and Hanzo, L. (2003) A Multicarrier DS-CDMA System Using Both Time-Domain and Frequency-Domain Spreading At of VTC'2003 (Fall), United States. 06 - 09 Oct 2003.

Record type: Conference or Workshop Item (Paper)


In this contribution we propose and study a multicarrier direct-sequence code-division multiple-access (MC DSCDMA) scheme, which employs both time (T)-domain and frequency (F)-domain spreading. We investigate the achievable detection performance in the context of synchronous TF-domain spread MC DS-CDMA, when communicating over an additive white Gaussian noise (AWGN) channel. The performance of three different detection schemes is investigated, which include the single-user correlation based detector, the joint TF-domain decorrelating multiuser detector (MUD) and the separate TF-domain decorrelating/MMSE MUD. Our simulation results show that the separate TF-domain decorrelating/MMSE MUD scheme is capable of achieving a better bit error rate (BER) performance than that of the significantly more complex joint TF-domain MUD schemes.
