| Abstract: | This paper interprets the MC-CDMA system with IBI as an equivalently time-domain intersymbol interference (ISI) corrupted direct sequence (DS-) CDMA system with specific spreading codes. Successively, based on this representation, a time-domain channel estimation method and its corresponding time-domain linear minimum mean square error (MMSE) multiuser detection scheme are derived for the MC-CDMA system with IBI. Computer simulations illustrate the overall performance of the proposed time-domain channel estimation and the corresponding multiuser detection scheme. |
