In this paper a time synchronization algorithm for IEEE 802.11a/g OFDM-WLAN standard is presented and some modifications are proposed to simplify its implementation without sacrifice its performance. To evaluate its feasibility this algorithm is compared with others found in the literature. The comparison of performance has been carried out by simulation in multipath channels, at low signal to noise ratios and with carrier frequency offset. It is shown that the proposed solution has a better performance and a lower computational cost.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
