摘要: For existing localization algorithms, Non-Line-of-Sight (NLOS) propagation introduces some problems for the determination of mobile position. This is because most these algorithms depend on information extracted from Line-of-Sight (LOS) path such as Time-of-Arrival (ToA) or Time-Difference-of-Arrival (TDoA) received by either one more Base Stations. On contrary, based Power Delay Profile Fingerprinting (PDP-F) take advantage uniqueness multipath channel between Station (BS) and Mobile (MS) over geographical region interest. The fingerprinting approach its name implies performs a matching simulated database quantity corresponding measured indicates match cost function two. In this paper, we introduce an extension to including effects Doppler shifts paths which call method (PDDP-F). With inclusion extra information, aim increase accuracy resolving not only in delay dimension but also dimension.
