However, blind channel estimation is a very complex, very fargoing research topic. Because of the author's limit ability and time, only the simple subspace channel estimation method is studied. In the third part of this dissertation, the subspace channel estimation method in MIMO-OFDM systems is investigated.

信道盲估计技术因为仅仅根据接收到的序列来估计信道而特别有吸引力，盲估计方法大大提高了通信系统的吞吐量，因此，MIMO-OFDM系统中的盲信道估计技术成为一个研究热点。

In this dissertation, the wave propagation characters in a helix type slow wave structure filled with plasma immersed in finitely strong confining magnetic field is systematically studied.

The above four aspect of Cosmology, Ontology, GungFuLun and JingJieLun that serve as the interpretational framework, will consist a set of theories, in there, every aspects are theoretically connected with each other inside the system of any particular schools.

上述宇宙论、本体论、工夫论、境界论的四方架构解释体系将以个别学派分开立论的形式形成各学派内部一致的理论系统，而不同学派之间就将有整个系统的差异。

By means of analyzing the difference between HVDC transmission line and traditional HVAC transmission lines, it is proved that it is not suitable to apply superposition principle to the power grid containing HVDC transmission lines, thus following conclusions are obtained: in the place near to HVDC transmission line the fundamental frequency fault component element should be not adopted; and there is definite relation between the maloperation of directional comparison pilot protection applied in practical project and the adoption of fundamental frequency fault component element.

通过分析HVDC的特性与传统交流系统的不同，证明叠加原理不能应用在含有HVDC的系统中，从而得出结论：在HVDC附近不应该采用工频故障分量元件，实际工程中的纵联方向保护误动作与使用工频故障分量元件有一定关系。

Closed cycle adjusts a circuit having applying broadly in navar , how a project is demanded but , change into the norm to navar technology function , is not at present still very clear and definite.

摘 要：闭环调节回路在控制系统中有广泛的应用，但如何将工程要求转化为对控制系统技术性能的规范，目前仍然不是十分的明确。

Therefore, the exact relation between the unbalanced input voltage and the noncharacteristic harmonics of the output voltage in the 12-pulse rectifier system is obtained. In addition, the relation between the input current and the imbalance of the input voltage is obtained, which could help to choose the filter elements and exactly analyze the characteristics of the no controlled rectifier circuit.

利用精确的开关函数，推导了多脉波整流系统输入不平衡电压与输出电压非特征谐波的精确关系，进而得到电阻、电感负载时系统输入电流与输入电压不平衡度的关系，为精确地选择滤波元件做了有意义的探索。

IiThe relations between a generalnonconservative system and the relatedconservative systems are investigated and aninteresting conclusion is drawn:the solutionsto a general nonconservative problem existin those of the related conservative problems.
