英文摘要: Ultrawide-Band(UWB) communication technology is the key candidate of the physical layer for the next generation wireless sensor networks(WSN). Multiple access synchronization technology is the one of supporting technologies realizing data acquisition, processing and transmission for UWBWSN. The project will make full use of research results in wireless communications and intelligent digital signal processing technologies to study multiple access synchronization methods and its performance in UWB communication systems. The project will focus on modeling the multiple access interfere, optimizing the pulse signal parameters and setting the dynamic threshold of synchronization systems through penetrating and merging some theories, methods and technologies, i.e., fuzzy control theory, optimization design and RBF neural network technology and so on. The aim is to design multiple access synchronization methods with high speed, high accuracy and high robust. WSN research is one hot spot, a revolution for information perception and acquisition, and is considered one of the most important technologies in the 21st century, and makes human life be far-reaching impact. Research results of this project have the important theoretical significance and practical value for the development of WSN and a very good application prospe
