Description: Timing Synchronization for 802.11a WLANs under Multipath Channels
In the Wireless Local Area Network
(WLAN) standard adopted by the IEEE 802.11a
standardization group, each data packet starts with a
preamble, which consists of ten short training symbols
followed by two long training symbols. In this paper,
we present an efficient and straightforward coarse
timing synchronization scheme based on the short
training symbols. Simulation results illustrate that the
performance of the proposed scheme is comparable
and even superior to that of the conventional timing
synchronization method under multipath fading
channels. We further show that the combination of
the proposed auto-correlation coarse timing
synchronization scheme and a frequency domain path
delay moving average method leads to a desirable
result of symbol timing estimation.
