Abstract:	An orthogonal frequency division multiplexing (OFDM) frequency division multiple access (FDMA) indoor geolocation system is discussed in this paper. The principle of operation, transmitter, channel, and receiver are discussed. The system’s theoretical performance and simulation results are presented. This system is an attractive alternative for indoor geolocation for the following reasons: (1) it appears that indoor positioning and navigation are achievable to within a few meters if only pseudorange measurements are used, and (2) the receiver design is far simpler than the design of any conventional GPS receiver.
