In this part, carrier interferometry technique is combined with MIMO-OFDM architechure, resulting in the so called MIMO-CI/OFDM system. It is shown that the novel system can achieve dramatic performance gains by taking advantage of large frequency diversity inherent in the CI/OFDM technique. Further more, the proposed MIMO-CI/OFDM system has a more stable envelope and, ultimately, an average PAPR far smaller than that of MIMO-OFDM.

将载波干涉技术与多天线OFDM技术相结合实现了一种MIMO-CI／OFDM结构，由于CI／OFDM具有大的频率分集作用，该结构因而获得显著的性能增益；而且由于采用CI技术使得发射信号的包络更加平稳，与原有的MIMO-OFDM系统相比具有较低的PAPR。
