In this paper , the constraint viterbi algorithm is studied from the project research on a novel product code and decode which is a project of national natural science foundation of china , experiment results show that it can overcome the drawback and reduce the decoding complexity while keeping the good characteristic of conventional viterbi algorithm 本文所研究的约束维特比算法基于国家科学基金项目《新一代乘积编码( productcode )及解码方法的研究》 ,不但保持了原有维特比算法的特性,而且在减少译码路径的情况下,能较好地解决上述问题。
Based on the above perception , we carried out systematic research on attitude control of a rigid body and its application to robot control . our research is supported partly by the national natural science foundation of china ( grant no . 69774010 ) , aeronautical science foundation of china ( grant no . 97d53040 ) and the national 973 fundamental research program of china ( grant no . g1988030417 ) . the main contributions of this dissertation are as follows : ( 1 ) four kinds of parameters for representing the attitude of a rigid body are studied 基于这样的认识，本文在国家自然科学基金项目“刚体姿态控制的几何方法” (基金代号： 69774010 ) 、航空科学基金项目“航空火控系统中的姿态控制问题” (基金代号： 97d53040 )和国家973重大基础研究项目“复杂大系统过程优化与高性能软件” (项目代号： g1988030417 )的资助下，对刚体姿态控制及其在机器人控制中的应用进行了较为系统的研究。
A damage imaging approach is adopted and improved to image the damage . the applicability and effectiveness of the proposed method is demonstrated by experimental studies . this research is supported by the national natural science foundation of china under grant no . 10572058 , and by the science foundation of aeronautics of china under grant no . 04i52063 本文的研究得到了国家自然科学基金项目,基于无线智能传感器网络复合材料结构健康监测的先进损伤识别技术(项目编号: 10572058 ) ,和航空科学基金项目,复合材料结构健康监测系统中的先进损伤识别技术(项目编号: 04i52063 )的资助。
Combined with the foundation research ( avigation science fund 04d52032 ) ” study on cfar detecting expert system base on clutter tracking ” . this paper study the fractal technic and snake algorithm on the application of clutter tracking . it proved that the method was effective by the algorithm which adapt to the real and simulant clutter data 本课题结合航空科学基金“基于杂波跟踪融合的恒虚警检测专家系统研究” ,研究分形技术和snake算法在杂波跟踪中应用,设计了相应的算法,通过分析真实数据和仿真数据验证了算法的有效性。
