Timing-synchronization analysis for IEEE 802.11 a wireless LANs on frequency- nonselective Rician fading channels

This paper derives and computes the probability of synchronization failure, P/sub fail/, for IEEE 802.11a wireless LANs on frequency-flat Rician fading channels. For a frequency offset within /spl plusmn/232 kHz, it is shown that its effect on the synchronization performance is minor. The E/sub ds//N/sub 0/ ratios required to achieve P/sub fail/ = 10/sup -3/ and 10/sup -4/ are computed, where E/sub ds/ is the data symbol energy. We find that E/sub ds//N/sub 0/ ratio over 20dB are generally required for channels with Rician factors K /spl les/ 6 dB. In particular, E/sub ds//N/sub 0/ ratios that yields P/sub fail/ = 10/sup -4/ exceed 30 dB for K /spl les/ 4 dB.
