本文提出并分析了基于全双工多输入多输出奇异值分解(FD-MIMO-SVD)的自干扰抵消(SIC)中继的性能。考虑了信源到中继和自干扰信道的信道估计误差的影响。研究了瑞利衰落信道中加性高斯白噪声(AWGN)对系统性能的影响。通过利用奇异值分解作为主要的本征模传输来最大化期望信号的信噪比(SNR)，并减轻自干扰(SI)，给出了该系统的分析结果。此外，还推导了M进制相移键控(MPSK)调制方案的信干噪比(SINR)分布和中断概率的精确封闭解，并与平均符号错误率(ASER)进行了评估。
In this paper, we propose and analyse the performance of the full-duplex multiple-input multiple-output singular value decomposition (FD-MIMO-SVD) based relay with self-interference-cancellation (SIC). The effects of channel estimation errors for the source-to-relay and self-interference channels are considered. The performance of the system is investigated in the presence of additive white Gaussian noise (AWGN) over Rayleigh fading channels. Analytical results are presented for this system by exploiting SVD as a dominant eigenmode transmission for maximizing the signal-to-noise ratio (SNR) of the desired signal, in addition to mitigating the self-interference (SI). Furthermore, exact, closed-form solutions for the signal-to-interference-plus-noise-ratio (SINR) distribution and outage probability are derived and evaluated along with the average symbol error rate (ASER) for M-ary phase-shift keying (MPSK) modulation schemes.
