| 摘 要： | 提出了一种MIMO同时同频全双工系统下的数字干扰对消算法,综合考虑了系统非线性对干扰对消的影响.该算法通过基于逐幸存路径处理的方法,对自干扰信号与待接收信号进行联合信道估计,采用维特比算法实现自干扰信号数字对消和待接收信号最大似然接收.通过对MIMO全双工系统仿真实验表明,该算法能够有效抑制系统非线性失真且有着良好的自干扰对消性能. |
| 关 键 词： | 全双工MIMO 数字对消 逐幸存路径处理 非线性失真 |

| Abstract: | In this paper, we propose a novel digital cancellation technique in full duplex MIMO wireless communication systems. The effect of non-linear distortions on self- interference cancellation in full duplex systems are considered. The proposed scheme are based on the Viterbi algorithm detection using Per-survivor processing (PSP) to jointly estimate the self-interference channel and the signal-of-interest channel. Simulation results illustrate that the proposed scheme is able to suppress the nonlinear distortion to the level of the significant noise component and has fairly desirable self-interference signal cancellation performance. |
| Keywords: | full duplex MIMO digital cancellation per-survivor processing non-linear distortions |
