53347 从系统可辨识性问题出发，对瞬时欠定盲源分离问题进行空间建模， Based on the identifiability of linear system, the paper models the problem of underdetermined blind source separation using a linear array.
53348 理论分析表明，当源信号在空间处在某些特定区域时，系统是不可辨识的，从而无法正确实现欠定盲源分离。 Theoretical analysis shows that an underdetermined system cannot be identified when sources are located in some areas and the problem of underdetermined blind source separation cannot be resolved.
53349 利用混合矩阵估计的克拉美罗界，进一步明确了影响系统可辨识性的源信号空间分布区域。 The areas where an underdetermined system cannot be identified are reconfirmed after the cramér-rao bound for estimating the mixing matrix in noisy sparse component analysis is deduced.
53350 仿真实验验证了理论分析的正确性。 Simulations confirm the theoretical analysis.
53351 本文根据传统的干扰对齐思想，在缩小干扰空间之间弦距的同时尽量增大信号-干扰空间之间弦距，以此为目标设计用户选择准则， With the insights from conventional interference alignment (IA), a user selection criterion is formulated not only to reduce the chordal distance between interference spaces, but also to enlarge that between the signal-interference spaces.
53352 并在接收端采用预处理矩阵智能选取技术最大化信道容量， Besides, at the receiver side, the post-processing matrix will be selected smartly to maximize channel capacity.
53353 提出了 3 用户 MIMO 干扰信道中稳健的机会干扰对齐方法。 With all have been mentioned, a robust opportunistic interference alignment (ROIA) method in 3 user MIMO interference channels (IC) is proposed.
53354 相比文献[1]方法，所提出的方法不但具有更高的系统瞬时性能稳健性，而且还具有更高的信道容量，只是在复杂度方面略有增加。 Compared with the OIA method in [1], the proposed method promises not only robustness in instantaneous performance but also higher capacity. But the system complexity increases slightly.
53355 仿真结果证明了本文方法的有效性。 The effectiveness of the proposed method is verified by simulation results.
53356 随着不断缩小的工艺尺寸，NBTI 为主导的老化因素对 VLSI 器件寿命的影响尤为突出。 With the shrink of technology scaling, it is significant that aging mainly caused by Negative-Bias-Temperature Instability (NBTI) influence on life of VLSI.
