Summary:
Orthogonal frequency division multiplexing (OFDM) combined with time division multiplexing (TDM) (called OFDM/TDM) using minimum mean square error (MMSE) frequency-domain equalization (FDE) can bridge the single carrier (SC) and the conventional OFDM transmissions while reducing the peak-to-average power ratio (PAPR) and maintaining the same data rate. Multi-carrier code division multiple access (MC-CDMA) with MMSE-FDE is one of the promising signaling techniques for future mobile communication systems. In this paper we present the performance comparison between OFDM/TDM and multi-code MC-CDMA with MMSE-FDE in a frequency-selective Rayleigh fading channel. The performance is evaluated in terms of average bit error rate (BER) by computer simulation. It is shown that uncoded OFDM/TDM achieves a lower BER performance in comparison to multi-code MC-CDMA while keeping the same data rate transmission and significantly reducing the PAPR. However, the coded BER performance of these two is almost the same.
