本文在不完全信道状态信息（CSI）条件下，对一种基于均衡转发（EF）中继和自干扰抵消（SIC）的全双工最大比组合多输入多输出（FD-MRC-MIMO）系统进行了性能分析。研究了在瑞利衰落信道中存在加性高斯白噪声（AWGN）时系统的性能。通过奇异值分解（SVD）应用零空间投影（NSP）实现自干扰消除。此外，精确的，封闭形式的解决方案的信号干扰加噪声比（SINR）分布和中断概率的数学公式和平均符号误码率（激光）的M-ary相移键控（M-PSK）调制的评估。为了使传输信号之间的均方误差（MMSE）最小，计算了电磁中继的系数。将获得的结果与相关的最先进技术进行比较，表明SINR数字和系统容量有了显着改善。
In this paper, the performance analysis of a full-duplex maximum ratio combining multiple-input multiple-output (FD-MRC-MIMO) system based on equalize-and-forward (EF) relaying with self-interference-cancellation (SIC) is derived under imperfect channels state information (CSI). The performance of the system is investigated in the presence of additive white Gaussian noise (AWGN) over Rayleigh fading channels. Self-interference cancellation is performed by applying null-space-projection (NSP) via singular-value-decomposition (SVD). Furthermore, exact, closed-form solutions for the signal-to-interference-plus-noise ratio (SINR) distribution and outage probability are mathematically formulated and evaluated along with the average symbol-error-rate (ASER) for M-ary phase-shift keying (M-PSK) modulation. The coefficients of the EF-relay are obtained to attain the minimum mean square error (MMSE) between the transmission symbols. Comparison of the obtained results with relevant state-of-the-art techniques suggests significant improvements in the SINR figures and system capacity.
