Along with the fast development of spread spectrum communication and global positioning system, varied signal forms are proposed, especially the emergence of BOC modulated signal leads to the characteristics of multi peaks and spectrum splitting. However, consider the need for the flexibility and extensible BOC signals application, a flexible control binary offset carrier modulation signal is proposed...
There are many defects in existing single system. A reconfigurable receive scheme based on multi-band signals was proposed, considering new job bands and the compatible of multiband. The process scheme was reasonably chosen by user demand, and the application analysis was carried out. Further, the main processes were described in this paper.
With the development of orbit transfer vehicle (OTV), attitude adjustment technology has become the focus of the research. For the necessary of interaction and extendibility which exit in the visual simulation of OTV attitude adjustment. According to the adjustment algorithm which based on OTV special attitude, technical assistance was provided by constructing the framework and function model of federation,...
At present, each industry has its own database system. Yet, the overall performance of the business systems is falling, with the increase of running time and the rapid growth of the amount of data. Data rapid finding program was designed in this paper, table partition and index partition technology were used in large oracle table, and fast data retrieval was completed.
According to the shortage of existing methods, a main peak estimate algorithm based on BOC(2n,n) signal was proposed. Further, the simulation analysis was implemented, and the validity of main peak estimate algorithm was proved. The result showed that the main peak was improved and the estimate accuracy was improved.
The main peak extraction method was proposed, considering the main peak uncertainty of multi-peak signal and the inadequateness of existing methods. The purpose of main peak extraction was achieved by relevant processing, and the ambiguity of sub-peak triggered was removed, the characteristic of single peak was restituted. In the same time the method was simulated, the conclusion proved that the main...
