A study of the wireless location technology in the celluar system
【Abstract】
Today wireless location is not only one of the ten popular telecommunication technologies, but also an important aspect of the third generation mobile telecommunication research. Firstly the paper generalizes the wireless location technology’s backgrounds, causes and practical applications, then discusses three kinds of wireless location schemes, including the location system based on the mobile station and the network, and the location system of admixture. We analyse several common mobile position technologies, compare their advantages and disadvantages, and point out the sources of error. In this paper, we analyse emphatically the principle of the celluar system’s position location techniques of TOA、TDOA、AOA, and compare their features by MATLAB. Finally, we expound the applications of the wireless location technology in the cellular system and point out some topics about wireless location which will be studied in the following days.
