多循环的

The theory and approach are introduced, and the general expression containing arbitrary parameter is obtained for the feedback gain matrix. This method changes the problem of multi-input system to several problems of single-input. The number is the cycle index of system matrix. Compare with some known results, this method put forward that the least number of unknown entries of the feedback gain matrix is the order of the system matrix.

This paper introduces a single-carrier system with hybrid time-frequency domain Decision Feedback Equalization, in which the short pn (Pseudo-Noise) sequence with fixed waveform replaces the cyclic prefix in the conventional Single Carrier systems with Frequency Domain Equalization, and the long PN sequences composed of several short pn sequences are employed as the channel training sequences to complete the initial estimation and tracking for fast-varying channel.

相分量算法不要求电力系统元件参数对称或循环对称、不利用多端口网络理论及理想变压器的移相，拓宽了故障计算的适用范围、简化了编程难度，并可推广到处理诸如线路换位不完全的参数不对称等其他电网不对称计算。

The proposed method can work well under asymmetry element parmeters, and it is not necessary to consider the phase shift of ideal transformer or using multi-port net theory, which make the proposed method more applicable and simplify the calculation program. The method is also capable of handling various unsymmetrical calcuations, such as the fault calcuation for power system without complete transposition.
