Positioning Algorithms Research Based On Radio Frequency Pattern Matching

With development of communication network positioning technology and corresponding services are studied.In this thesis,"Radio Frequency Pattern Matching" technique has been studied. It needs no additional equipment to the existing networks and unsensitive to the channel states compared with Time of arrival schemes. The closed form expressions of Cramer-Rao bound is presented in this paper under the assumption of the two-dimensional positioning. And then Cramer-Rao bound is used for accuracy evaluation and comparison. Simulation results illustrate that the proposed method is valid.
