Research Of Compression Perception In Intelligent Building Wireless Communication Network

With the development of economy,the technology of network communication plays an important role in the development of information technology in China.The automatic monitoring for the building equipment by computer technology and network technology provide users with convenient services and promote the generation of intelligent building systems.With the maturity of intelligent building,people need more efficiency and safety for building.In order to obtain the high efficiency and accuracy of monitoring system,we should manage the information more efficiently and collect the data more sufficiently.With the extended band of the transmission signal,it is difficult to match the need for people based on the traditional sampling theorem.Finding a new sampling technology in wireless transmission plays an important role in the development of intelligent building monitoring system.In order to construct a complete wireless communication system,we should utilize spectrum resources more efficiently,which could improve the building safety and convenience.In this paper,we analysis the practicability of intelligent building monitoring system based on the survey of the modern wireless communication.Meanwhile,we do the research in the following aspects.Firstly,we give the demand for wireless communication technology system of intelligent building.Secondly,some spectrum detection methods are introduced.Thirdly,we introduce the OFDM into our intelligent building monitoring system.Based on OFDM,we introduce the compressive sensing into the channel estimation of OFDM system,which sufficiently utilizes the spectrum resource to increase the robust of the wireless communication system.Based on the technology above,the safety of intelligent building monitoring system could be improved.
