摘　　要：通用滤波器多载波(Universal filtered multi-carrier,UFMC)是第5代(Fifth generation,5G)候选波形之一,与正交频分复用(Orthogonal frequency division multiplexing,OFDM)相比具有更低的旁瓣泄露,通过对连续的子载波进行滤波处理,可支持离散的频谱异步通信。为了分析UFMC在多输入多输出(Multiple input multiple output,MIMO)系统中的抗载波频偏(Carrier frequency offset,CFO)鲁棒性,该文考虑数据流数为4,收发天线数为8×4的瑞利信道模型。仿真结果表明,UFMC-MIMO比OFDM-MIMO具有更好的抗载波频偏性能。The universal filtered multi-carrier （ UFMC ） is one of the f if th generation （ 5G） candidate waveforms. Compared with the traditional orthogonal frequency division multiplexing （ OFDM ） , the UFMC has the lower side-lobe level and can support fragment spectrum asynchronous communication by filtering successive carriers. In order to analyze the robustness of anti-carrier frequency offset （CFO） of UFMC in the multiple input multiple output （ MIMO） system, the Rayleigh fading channel model with 4 transmitted streams and 8 x 4 transceiver is considered here. The experimental results show that the UFMC-MIMO has the better anti-carrier frequency offset performance than OFDM- MIMO.
