Research On Transmission Technology Of Spectrum Sensing System Based On Mobile Terminal

With the continuous development of wireless communication technology and spectrum sensing technology,mobile interconnection oriented intelligent spectrum monitoring system has become the mainstream.However,the wireless network environment often has long time delay and high bit error rate,connection interruption,which will seriously affect the user experience.Under the background of intelligent spectrum monitoring system in mobile Internet application,around the data characteristic of system and working environment,this paper will describe data network transmission performance optimization.First,this paper analyzes the spectrum monitoring system for intelligent communication working environment and summarizes the system in the actual operation problems existing in the process of data transmission.Secondly,in view of the problem of disconnection in the system,this paper improves the long heartbeat strategy based on the classic heartbeat case,and improves the mechanism of disconnection.Thirdly,in view of the spectrum monitoring system of a large number of small file transfer problem,puts forward the algorithm of adaptive adjustment file compression level.Finally,in order to solve the problem of data transmission in the system,the transmission speed is improved adaptively,and the optimal speed matching transmission strategy based on learning is realized.According to the above improvement strategy,through its application to an actual project was studied.The experiment shows that the communication link does not appear frequently disconnected,and the real time and reliability of file transmission are improved Finally,the effectiveness of the above strategies for improving the performance of spectrum monitoring system is verified.
