MC-CDMA was born in February 1993, Nathan Yee proposed the original MC-CDMA system in \cite{Yee/Linnartz/Fettweis:1993} where serial to parallel converted bits are directly fed into the input of IFFT processor after coding applied, such that the number of subcarriers in the OFDM system equals to the code length of applied code. It can be seen that the same data symbol is duplicated in multiple carriers of OFDM symbol with the application of assigned code.
User $u_{0}$ take the code sequence $\textbf{C}_{0}$ where $\textbf{C}_{0} {}={} [c_{0,0},c_{0,1},\ldots,c_{0,M-1}]$ and the number of subcarriers of OFDM symbol $M_{d}$ in this case is equal to $M$. — Preceding unsigned comment added by Nuwankumara (talk • contribs) 08:51, 1 August 2011 (UTC)[reply]
