Abstract: Two novel STTD scheme in CDMA system which combine the advantage of combating fading and improving the capacity of the spatial time transmit diversity (STTD) with the advantage of high efficiency of spectrum and robustness to the frequency selective channel of the multi-carrier code division multiple access (MC-CDMA) are proposed in this paper,the application of the two scheme in MIMO MC-CDMA system is also studied,we compared and simulated the proposed two scheme with the conventional STTD based on the spatial time block code (STBC) in MIMO CDMA system and MIMO MC-CDMA system respectively.

Key words: multiple input &, multiple output, MC-CDMA, spatial time transmit diversity(STTD), spatial time block code(STBC)
