英文摘要： With the rapid development of the Internet as well as the popularity of the mobile devices, Wireless Local Area Network (WLAN) has been widely applied to human lives. Considered as a research hotspot in wireless communication technology nowadays, the relationship between wireless signals and human activities attracts people's attention. Based on the existing Wireless Local Area Network, researchers can develop indoor wireless positioning technology, and even human behavior detection technology. The high-density-low-cost characteristic of the Wireless Local Area Network makes the development of these kinds of indoor technologies more competitive than others. However, due to the complexity of the indoor environment, the development of indoor Wireless Local Area Network technology faces crucial challenges, and the main reason is that wireless signals will be interfered seriously due to the complexity of the indoor environment, such as multipath. We propose to conduct researches on indoor wireless positioning technology with physical layer information in this project, due to the fact that all these standard are based on Orthogonal Frequency Division Multiplexing (OFDM) technology at physical layer of the network. Indoor wireless network technology with physical layer information will effectively eliminate the signal interferences cause by the complexity of indoor environment, and thus improve the relevance of signals and human behaviors, and will achieve real effective indoor wireless positioning.We plan to publish 15-20 papers in top conferences and journals, file 5-8 patents, so keep the leading impact of our research group.
