介绍了一种适用于多载波码分多址系统的空频分组码的高效实现方法，并将其与不同的低复杂度单用户预均衡技术相结合应用于MC-CDMA系统的上行链路中。该方法可以完全避免接收端的均衡，并且不需要任何上行链路信道估计。研究表明，在MC-CDMA系统中，将SFBC与预均衡相结合可以在衰落信道中获得良好的性能。
In this paper, an efficient realization of space frequency block coding (SFBC) for OFDM systems is introduced and its combination with different low complexity single user pre-equalization techniques in the uplink of MC-CDMA systems is proposed. This approach can completely avoid an equalization at the receiver side and, additionally, does not need any uplink channel estimation. It is shown in this paper that the combination of SFBC with pre-equalization in MC-CDMA systems can achieve promising performance results in fading channels.
