盲均衡算法中常数模(CMA)和判决引导(DD)模式适时切换可以有效提高算法收敛速度和均衡性能,但是切换时机难以选择,同时在信道突发干扰条件下无法保证算法的稳健性。为此结合CMA和DD算法代价函数构造了一种动态目标函数,目标函数随着均衡算法迭代次数进行调整,以前馈神经网络(FNN)作为盲均衡器实现信道均衡,并以移动窗剩余误差变化率为判据对目标函数进行适时重置克服信道可能的突发干扰。计算机仿真表明了算法的有效性。

＜正＞This paper studies the linearization of a similar large-scale nonlinear control system using differential geometry methods. The large-scale nonlinear control system consists of N n-dimensional subsystems which have similar characteristic and relation. It is shown that the large-scale nonlinear control system is linearizable at the neighbour of one point if and only if each subsystem has m output functions and the sum of the corresponding characteristic index is equal to the dimension of the subspace n. and the index matrix has rank m.

Dynamic color is an important carrier that takes information in some special ***,up to the present,there are no available and objective tests to evaluate dynamic color *** investigate the characteristics of dynamic color processing,we adopted two patterns of visual stimulus called "onset-offset" which reflected static color stimuli and "sustained moving" without abrupt mode which reflected dynamic color stimuli to evoke event-related brain potentials (ERPs) in primary color amblyopia patients (abnormal group) and subjects with normal color recognition ability (normal group).ERPs were recorded by Neuroscan *** results showed that in the normal group,ERPs in response to the dynamic red stimulus showed frontal positive amplitudes with a latency of about 180 ms,a negative peak at about 240 ms and a peak latency of the late positive potential (LPP) in a time window between 290 and 580 *** the abnormal group,ERPs in response to the dynamic red stimulus were fully lost and characterized by vanished amplitudes between 0 and 800 *** significant difference was noted in ERPs in response to the dynamic green and blue stimulus between the two groups (P>0.05).ERPs of the two groups in response to the static red,green and blue stimulus were not much different,showing a transient negative peak at about 170 ms and a peak latency of LPP in a time window between 350 and 650 *** results first revealed that some subjects who were not identified as color blindness under static color recognition could not completely apperceive a sort of dynamic red stimulus by ERPs,which was called "dynamic red blindness".Furthermore,these results also indicated that low-frequency ERPs induced by "sustained moving" may be a good and new method to test dynamic color perception competence.
