Abstract: With the development of communication technology, wireless positioning technology is widely used in all sectors of society. This paper firstly analyzes the model of TDOA technology and realizes the location of a mobile station through an algorithm. Secondly, TDOA technology is applied in locating the bad network of wireless network optimization system. At last, this paper uses Matlab to simulate the location of mobile station based on four base stations and get an ideal simulation result.

Key words: wireless positioning, network optimization system, TDOA
