Which areas of our country are the most suitable of building wind power and photoelectric power and both complementary regional power generation systems are gained by the research on the distribution of wind and solar resources. On the basis of above, the basic structure and automatic control of complementary regional power generation system are designed to adapt to the areas, and the economic benefit...
The Orthogonal Frequency Division Multiplexing (OFDM) is widely used in high speed wireless communication owing to its high utilization rate in frequency spectrum and its availability in anti-multipath, but exorbitant peak-to-average power ratio(PAR) is a big obstacle to utilize it. This paper presents two kinds of common techniques to reduce peak-to-average power ratio, compares their performance...
At present, PID controller is widely used, but when the controlled object is more complex, the control effect of the general PID controller is worse, in order to improve the control performance of complex systems, a new approach to design fuzzy PID controller is introduced in the paper. In order to improve the accuracy of control, the fuzzy adaptive PID controller is further advanced in the paper,...
In the development and improvement of network management system(NMS), evaluation technology of NMS is a very important assistant tool. This paper describes the basic principle of evaluation technology, then discusses and studies the evaluation indexes in details from function, efficiency and survivability evaluation aspects. Finally, a computer stimulation system of evaluation is completed using Microsoft...
This paper analyzes the synchronization problem of OFDM in FH communication system, studies timing synchronization and frequency synchronization using pilots according to the characterization of OFDM and FH. This algorithm determines the time position and frequency offset using the correlation of the pilots. The research result indicates that this algorithm is available in the FH system.
The limited buffers consist generally in the process of practical production, and different production lines may manufacture different products. Based on the problem above, an interaction structure of up-down stream with limited buffers and the production scheduling model for minimal cost of subsidiary production and synchronous subsidiary production is established. The simplex algorithm and scheduling...
