Timing-based location estimation for OFDM signals with application in LTE, WLAN and WIMAX

This paper studies different coarse positioning techniques for wireless networks using orthogonal frequency division multiplexing (OFDM) signals. The methods under study are based on timing synchronization algorithms and various preambles embedded in the OFDM signal. Also correlation-based approaches and Multiple Signal Classification (MUSIC) approaches are investigated. The performance of the studied estimation algorithms is analyzed in terms of root mean square error (RMSE), obtained from computer simulation results and the aim is to provide a detailed comparison of various OFDM preamble-based timing estimators.
