Abstract:	An Orthogonal Frequency Division Multiplexing (OFDM) Frequency Division Multiple Access (FDMA) indoor geolocation system is discussed in this paper. The idea of a DSL signal structure is enhanced and applied to the problem of indoor positioning. The principle of operation, transmitter, channel, and receiver are discussed in this paper. The system theoretical performance and simulation results are presented in the paper. This system is an attractive alternative for indoor geolocation for the following reasons. (1) It appears that indoor positioning and navigation is achievable to within a few meters if only pseudorange measurements are utilized. (2) The receiver design is far simpler than any design of a conventional GPS receiver.
