Abstract-This paper derives and computes the probability of synchronization failure fail for IEEE 802.11a wireless LANs on frequency-flat Rician fading channels. For a frequency offset within 232 kHz, it is shown that its effect on the synchronization performance is minor. The ds 0 ratios required to achieve fail = 10 3 and 10 4 are computed, where ds is the data-symbol energy. We find that ds 0 ratios over 20 dB are generally required for channels with Rician factors 6 dB. In particular, ds 0 ratios that yield fail = 10 4 exceed 30 dB for 4 dB.Index Terms-Frequency-nonselective channel, IEEE 802.11a, orthogonal frequency division multiplexing (OFDM), probability of synchronization failure, Rician fading, sliding correlator, timing synchronization, wireless local area network (LAN).
This paper derives and computes the probability of synchronization failure, P fail , for IEEE 802.11a wireless LANs on frequency-flat Rician fading channels. For a frequency offset within ±232kHz, it is shown that its effect on the synchronization performance is minor. The E N ds 0 ratios required to achieve P fail = 10 3 and 10 4 are computed, where E ds is the data-symbol energy. We find that E N ds 0 ratios over 20dB are generally required for channels with Rician factors K ≤ ≤ ≤ ≤ 6dB. In particular, E N ds 0 ratios that yield P fail = 10 4 exceed 30dB for K ≤ ≤ ≤ ≤ 4dB.
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.
